TMS6100

Last updated

The Texas Instruments TMS6100 Voice Synthesis Memory (VSM) is a 1 or 4-bit serial mask factory-programmed read-only memory IC. [1] It is a companion chip to the TMS5100, CD2802, TMS5110, (rarely) TMS5200, and (rarely) TMS5220 speech synthesizer ICs, and was mask-programmed with LPC data required for a specific product. It holds 128 Kib (16 KiB) of data, and is mask-programmed with a start address for said data on a 16 KiB boundary. It is also mask-programmable whether the /CE line needs to be high or low to activate, and also what the two (or four) 'internal' CE bits need to be set to activate, effectively making the total addressable area 18 bits. Finally, it is mask-programmable whether the bits are read out 1-bit serially or 4 at a time.

TMS6125

The TMS6125 is a smaller, 32 Kib (4 KiB) version of effectively the same chip, with some minor changes to the 'address load' command format to reflect its smaller size.[ citation needed ]

Texas Instruments calls both of these serial roms (TMS6100 and TMS6125) "VSM"s (Voice Synthesis Memory) on their datasheets and literature. [1]

Both VSMs use 'local addressing', meaning the chip keeps track of its own address pointer once loaded. Hence every bit in the chip can be sequentially read out, even though internally the chip stores data in 8-bit bytes.

(For the following section, CE stands for "Chip Enable" and is used as a way to enable one specific VSM.)

Commands

The VSM has supports 4 basic commands, based on two input pins called 'M0' and 'M1': [1]

Part Numbering

When used on Texas Instruments' Consumer Division products, the VSMs are always marked CDxxxxx where xxxxx is a 4 or 5 digit mask rom ID code, typically 23xx or 62xxx. The chips are SOMETIMES (typically after 1981) also marked TMC0350, as this seems to be the 'internal use class' of the chip. The very first VSMs (used in the Speak and Spell, 1978 version) were marked TMC0351 and TMC0352 and did not have a CD number. These two SEEM to have been 'grandfathered in' as CD2300 and CD2301, as all later VSMs start at CD2302 (used in the 'Vowel Power' Speak and Spell expansion cartridge). It should also be noted that CD22xx, CD25xx and CD28xx numbers are used for chips that are NOT VSMs.[ citation needed ]

When used on Texas Instruments' non-consumer division products (such as generic voice chips for other computers/measurement devices which were still TI-branded) the chips are labeled VMxxxxx.

When used on 3rd party products, the chips are marked CMxxxxx instead. The numbering scheme for the xxxxx part seems to be common between both CDxxxxx and CMxxxxx chips (but NOT VMxxxxx chips), so no chip of either series will have a common xxxxx number.

With the revenue from the Z80, the company built its own chip factories and grew to over a thousand employees over the following two years.

The Intel 8085 ("eighty-eighty-five") is an 8-bit microprocessor produced by Intel and introduced in March 1976. It is software-binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features. However, it requires less support circuitry, allowing simpler and less expensive microcomputer systems to be built. The "5" in the part number highlighted the fact that the 8085 uses a single +5-volt (V) power supply by using depletion-mode transistors, rather than requiring the +5 V, −5 V and +12 V supplies needed by the 8080. This capability matched that of the competing Z80, a popular 8080-derived CPU introduced the year before. These processors could be used in computers running the CP/M operating system.
