Electronics industry in the Socialist Republic of Romania

Last updated

The electronics industry in the Socialist Republic of Romania was characterized by stronger ties to Western Europe when compared to other countries in the Eastern Bloc due to the drive of the Romanian leadership towards greater autonomy from the Soviet Union. [1]

In 1960 the government of Gheorghe Gheorghiu-Dej decided to build an electronics plant in the forest of Băneasa, which in 1962 was named Baneasa Radio and Semiconductor Parts Company (Romanian : Întreprinderea de piese radio și semiconductori or I.P.R.S.). [2] The production of integrated circuits started in 1970 with technology from Thomson-CSF. [3] : 7  The plant developed steadily and grew to 6,000 employees by the early 1980s. [2] By 1990, the product range included bipolar digital and linear integrated circuits (including 7400 series integrated circuits), silicon transistors and diodes, microwave devices, thyristors, triacs, and capacitors. [4] [5] I.P.R.S. manufactured with the designation βP14500 a clone of the 1-bit-microprocessor Motorola MC14500B in I2L technology. [5]

In 1969 the Research Center for the Design of Electronic Components (Romanian : Centrul de Cercetare Proiectare pentru Componente Electronice or CCPCE) was established on the grounds of I.P.R.S. but independent from it. [6] The research center developed semiconductor products from initial experiments to pilot production, at which point the mass manufacturing was handed over to I.P.R.S. By 1974 the center moved to a new headquarter adjacent to I.P.R.S. and changed its name to Research Institute for Electronic Components (Romanian : Institutul de Cercetare pentru Componente Electronice or ICCE). [6] With new production facilities opened in 1979 the institute started to manufacture transistors, diodes, integrated circuits, optoelectronics, and microwave devices for end customers, in particular products that were needed only in small quantities (a few thousand per month) and could therefore not be manufactured economically at I.P.R.S. [6]

A third entity, Microelectronica was set up in 1981 close to I.P.R.S. and ICCE with the goal of manufacturing PMOS, NMOS, and CMOS integrated circuits (including 4000-series integrated circuits) as well as optoelectronics, complementing the production profile of I.P.R.S. [4] [6] [7] Microelectronica manufactured a clone of the Intel 8080 with the designation MMN8080 [4] [8] and a clone of the Zilog Z80 with the designation MMN80CPU. [4] : 661  The MMN80CPU entered production in 1988. [7] For comparison, the original Z80 was launched in 1976 and the East German clone U880 in 1980.

After 1990

I.P.R.S. remained in government hands until 2003. [2] After a factory upgrade in 1992 a steady decline set in. [2] The number of employees dropped to 5000 in 1991 and 2000 at the end of the 1990s. [2] Amid allegations of corruption, the plant was sold in 2003 to Syrian businessman Omar Hayssam (who was in 2013 sentenced to a 20-year prison term for organizing the kidnapping of three Romanian journalists in Baghdad). [3] : 18  By 2008, I.P.R.S. was declared bankrupt. The equipment had been stolen or sold for scrap at that point. [3] : 18 

ICCE was first split into four sections but largely re-united in 1996 as the Institute for Microtechnology (Romanian : Institut de Microtehnologii or IMT). [6] [9] While IMT still existed in 2020, it has lost its commercial manufacturing capabilities as well as its industry partners I.P.R.S. and Microelectronica. [6]

Microelectronica ceased commercial operation in 1997, and many of its specialists transferred to IMT. [9] As of 2020, Microelectronica still exists as a "technology showcase", albeit without any products and few employees. [7] [3] : 19 

Semiconductor designation

Unlike the Soviet integrated circuit designation or the East German semiconductor designation, the Romanian government did not set standards for the labeling of semiconductors. Devices licensed from Western manufacturers were often named according to the Pro Electron standard. Microelectronica assigned integrated circuit designations according to the underlying technology: [4] : 582  MMP for PMOS (e.g. MMP106), [10] MMN for NMOS (e.g. MMN8080), [10] and MMC for CMOS (e.g. MMC4001).

An integrated circuit, also known as a microchip, chip or IC, is a small electronic device made up of multiple interconnected electronic components such as transistors, resistors, and capacitors.

<span class="mw-page-title-main">Latch-up</span> Short circuit which can occur in MOSFET circuits

In electronics, a latch-up is a type of short circuit which can occur in an integrated circuit (IC). More specifically, it is the inadvertent creation of a low-impedance path between the power supply rails of a MOSFET circuit, triggering a parasitic structure which disrupts proper functioning of the part, possibly even leading to its destruction due to overcurrent. A power cycle is required to correct this situation.

In integrated circuits, depletion-load NMOS is a form of digital logic family that uses only a single power supply voltage, unlike earlier NMOS logic families that needed more than one different power supply voltage. Although manufacturing these integrated circuits required additional processing steps, improved switching speed and the elimination of the extra power supply made this logic family the preferred choice for many microprocessors and other logic elements.

An active-pixel sensor (APS) is an image sensor, which was invented by Peter J.W. Noble in 1968, where each pixel sensor unit cell has a photodetector and one or more active transistors. In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as amplifiers. There are different types of APS, including the early NMOS APS and the now much more common complementary MOS (CMOS) APS, also known as the CMOS sensor. CMOS sensors are used in digital camera technologies such as cell phone cameras, web cameras, most modern digital pocket cameras, most digital single-lens reflex cameras (DSLRs), mirrorless interchangeable-lens cameras (MILCs), and lensless imaging for cells.

<span class="mw-page-title-main">KR580VM80A</span> 8-bit microprocessor

The KR580VM80A is a Soviet microprocessor, a clone of the Intel 8080 CPU. Different versions of this CPU were manufactured beginning in the late 1970s, the earliest known use being in the SM1800 computer in 1979. Initially called the K580IK80 (К580ИК80), it was produced in a 48-pin planar metal-ceramic package. Later, a version in a PDIP-40 package was produced and was named the KR580IK80A (КР580ИК80А). The pin layout of the latter completely matched that of Intel's 8080A CPU. In 1986 this CPU received a new part number to conform with the 1980 Soviet integrated circuit designation and became known as the KR580VM80A (КР580ВМ80А), the number it is most widely known by today. Normal clock frequency for the K580IK80A is 2 MHz, with speeds up to 2.5 MHz for the KR580VM80A. The KR580IK80A was manufactured in a 6 µm process. In the later KR580VM80A the feature size was reduced to 5 µm and the die became 20% smaller.

The NEC μCOM series is a series of microprocessors and microcontrollers manufactured by NEC in the 1970s and 1980s. The initial entries in the series were custom-designed 4 and 16-bit designs, but later models in the series were mostly based on the Intel 8080 and Zilog Z80 8-bit designs, and later, the Intel 8086 16-bit design. Most of the line was replaced in 1984 by the NEC V20, an Intel 8088 clone.
