Product Summary

The PSD312-B-70 is a Field-Programmable Microcontroller Peripheral. The device integrates high-performance and user-configurable blocks of EPROM, programmable logic, and optional SRAM into one part. The PSD312-B-70 also provides a powerful microcontroller interface that eliminates the need for external glue logic. The device is ideal part for interfacing to virtually any microcontroller. The PSD312-B-70 can efficiently interface with, and enhance, almost any 8- or 16-bit microcontroller system.

Parametrics

PSD312-B-70 absolute maximum ratings: (1)TSTG, Storage Temperature: –65 to +150℃; (2)Voltage on any Pin With Respect to GND: –0.6 to +7V; (3)VPP, Programming Supply Voltage With Respect to GND: –0.6 to +14V; (4)VCC, Supply Voltage With Respect to GND: –0.6 to +7V; (5)ESD Protection: >2000V.

Features

PSD312-B-70 features: (1)Single-chip programmable peripheral for microcontroller-based applications; (2)Configurable as 32, 64, or 128 K x 8; or as 16, 32, or 64 K x16; (3)Divided into eight equally-sized mappable blocks for optimized address mapping; (4)As fast as 70 ns access time, which includes address decoding; (5)Optional 16 Kbit SRAM is configurable as 2K x 8 or 1K x 16. The access time can be as quick as 70 ns, including address decoding; (6)Ability to interface to multiplexed and non-multiplexed buses; (7)Built-in address latches for multiplexed address/data bus; (8)ALE and Reset polarity are programmable (Reset polarity not programmable on V-versions); (9)Multiple configurations are possible for interface to many different microcontrollers; (10)Optional built-in page logic expands the MCU address space by up to 16 times.
