ALTERA - EP1200-ES - Programmable Logic Device

FPGA - Field Programmable Gate Array

Altera EP1200 was the first high-density programmable logic device (PLD). Altera’s technology was manufactured using 3-μm complementary metal oxide semiconductor (CMOS) electrically programmable read-only memory (EPROM) technology and required ultraviolet light to erase the programming, whereas Xilinx’s technology was based on conventional static random access memory (SRAM) technology and required an EPROM to store the programming.

Altera EP1200 programmable logic device was introduced in 1985. The device used UV erasable technology and could hold the equivalent of 1200 logic gates.

When Introduced in 1985 the cost of the EP1200-ES FPGA cost was $129.50 each in quantities of 100.

The Altera PLE-12 Master Progamming unit and similar are used to program EP300, EP320, EP1200, and EP1210 devices.

Hitachi - HN27C256AG-10 - UV Erasable Programmable ROM, 32768-word × 8-bit

Hitachi HN27C256AG is a 256-kbit ultraviolet erasable and electrically programmable ROM, featuring high speed and low power dissipation. Fabricated on advanced fine process and high speed circuitry technique, the HN27C256AG makes high speed access time possible for 16 bit microprocessors such as the 8086 and 68000. And low power dissipation in active and standby modes matches our CMOS 256-kbit EPROM. In programming operation, the HN27C256AG realizes faster programming times than our conventional 256-kbit EPROM by Hitachi’s Fast High-Reliability Programming Algorithm. Pin arrangement, pin configuration and programming voltage are compatible with our 256-kbit EPROM series, therefore existing programmers can be used with the HN27C256AG.

High speed -Access time: 100 ns (max)

• Low power dissipation - Active mode: 25 mW (typ) (f = 1 MHz), Standby mode: 5 µW (typ)
• High reliability and fast programming - Programming voltage: +12.5 V DC

MITSUBISHI - M5K4164ANP-15 IC, Memory.

This is a family of 65 536-word by l-bit dynamic RAMs, fabricated with the high performance N-channel silicon gate MOS process, and is ideal for large-capacity memory systems where high speed, low power dissipation, and low costs are essential. The use of double-layer polysilicon process technology and a single-transistor dynamic storage cell privide high circuit density at reduced costs, and the use of dynamic circuitry including sense amplifiers assures low power dissipation. Multiplexed address inputs permit both a reduction in pins to the standard 16-pin package configuration and an increase in system densities. The M5K4164ANP operates on a 5V power supply using the on-chip substrate bias generator.
