MSM81C55-5RS - 2048 Bit CMOS Static RAM With I/O Ports and Timer
Description
The MSM81C55-5 has a 2k-bit static RAM (256 bytes) with parallel
I/O ports and a timer. It uses silicon gate CMOS technology and
consumes a standby current of 100 micro ampere, maximum, while
the chip is not selected. Featureing a maximum access time of 400
ns, the MSM81C55-5 can be used in an MSM80C85AH system without
using wait states. The parallel I/O consists of two 8-bit ports and one
6-bit port (both general purpose).
The MSM81C55-5 also contains a 14-bit programmable counter/timer
which may be used for sequence-wave generation or terminal count-pulsing.
Features
• High speed and low power achieved with silicon gate CMOS technology
• 256 words x 8bits RAM
• Single power supply, 3 to 6 V
• Completely static operation
• On-chip address latch
• 8-bit programmable I/O ports (port A and B)
• TTL Compatible
• RAM data hold characteristic at 2 V
• 6-bit programmable I/O port (port C)
• 14-bit programmable binary counter/timer
• Multiplexed address/data bus
• Direct interface with MSM80C85AH
• 40-pin Plastic DIP (DIP40-P-600-2.54): (Product name: MSM81C55-5RS)
• 44-pin Plastic QFJ (QFJ44-P-S650-1.27): (Product name: MSM81C55-5JS)
• 44-pin Plastic QFP (QFP44-P-910-0.80-2K): (Product name: MSM81C55-5GS-2K)
