Zilog Encore! 32

Last updated

Zilog Encore! 32 is an ARM9-based microcontroller by Zilog, Inc. It was the company's second attempt to produce ARM-based controllers.

ARM9 is a group of older 32-bit RISC ARM processor cores licensed by ARM Holdings for microcontroller use. The ARM9 core family consists of ARM9TDMI, ARM940T, ARM9E-S, ARM966E-S, ARM920T, ARM922T, ARM946E-S, ARM9EJ-S, ARM926EJ-S, ARM968E-S, ARM996HS. Since ARM9 cores were released from 1998 to 2006, they are no longer recommended for new IC designs, instead ARM Cortex-A, ARM Cortex-M, ARM Cortex-R cores are preferred.

Microcontroller small computer on a single integrated circuit

A microcontroller is a small computer on a single integrated circuit. In modern terminology, it is similar to, but less sophisticated than, a system on a chip (SoC); an SoC may include a microcontroller as one of its components. A microcontroller contains one or more CPUs along with memory and programmable input/output peripherals. Program memory in the form of ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips.

Zilog American manufacturer

Zilog, Inc. is an American manufacturer of 8-bit and 16-bit microcontrollers. Its most famous product is the Z80 series of 8-bit microprocessors that were compatible with the Intel 8080 but significantly cheaper. The Z80 was widely used during the 1980s in many popular home computers such as the TRS-80 and the ZX Spectrum, as well as arcade games such as Pac-Man. The company also made 16- and 32-bit processors, but these did not see widespread use. From the 1990s, the company focused primarily on the microcontroller market.

This system-on-a-chip includes an integrated memory controller, interfaces such as Universal Serial Bus (USB), liquid crystal display (LCD) and Serial Peripheral Interface Bus (SPI).

The memory controller is a digital circuit that manages the flow of data going to and from the computer's main memory. A memory controller can be a separate chip or integrated into another chip, such as being placed on the same die or as an integral part of a microprocessor; in the latter case, it is usually called an integrated memory controller (IMC). A memory controller is sometimes also called a memory chip controller (MCC) or a memory controller unit (MCU).

Variants include version supporting magnetic stripe reader or smart card reader.

Smart card pocket-sized card with embedded integrated circuits

A smart card, chip card, or integrated circuit card (ICC) is a physical electronic authorization device, used to control access to a resource. It is typically a plastic credit card sized card with an embedded integrated circuit. Many smart cards include a pattern of metal contacts to electrically connect to the internal chip. Others are contactless, and some are both. Smart cards can provide personal identification, authentication, data storage, and application processing. Applications include identification, financial, mobile phones (SIM), public transit, computer security, schools, and healthcare. Smart cards may provide strong security authentication for single sign-on (SSO) within organizations. Several nations have deployed smart cards throughout their populations.

Toolkit also includes Linux support.

Specifications

The External Bus Interface, usually shortened to EBI, is a computer bus for interfacing small peripheral devices like flash memory with the processor. It is used to expand the internal bus of the processor to enable connection with external memories or other peripherals. EBI can be used to share I/O pins controlling memory devices that are connected to two different memory controllers. Use of EBI reduces the total number of system pins required causing the system cost to come down. EBI manufacturers include Barco, Freescale Semiconductor,, Microchip, Atmel, and Silicon Labs.
