Description

The ZPSD302B-90JI is a kind of single-chip programmable peripheral for microcontroller-based applications. ZPSD302B-90JI integrates high-performance and user-configurable blocks of EPROM, programmable logic, and optional SRAM into one part. The major functional blocks include two programmable logic arrays, 256Kb to 1 Mb of EPROM, optional 16 Kb SRAM, input latches, programmable I/O ports, page logic and programmable security. Besides, it is available in 44 pin PLDCC package, industrial temperature range.

There are some features of ZPSD302B-90JI as follows. (1) optional 16 Kbit SRAM is configurable as 2K*8 or 1K*16. The access time can be as quick as 90 ns, including address decoding; (2) optional built-in page logic expands the MCU address space by up to 16 times; (3) programmable power management with standby current as low as 1A for low-voltage version; (4) track mode that allows other microcontrollers or host processors to share access to the local data bus; (6) wide operating voltage range: 4.5 to 5.5 volts; (7) simple, menu-driven software (PSDsoft) allows configuration and design entry on a PC; (8) two Programmable Arrays (PAD A and PAD B) replace your PLD or decoder.

What comes next is about the absolute maximum ratings of ZPSD302B-90JI. (1): TSTG (storage temperature) is from -65 to +150 for CERDIP and from -65 to +125 for PLASTIC; (2): voltage on any pin with respect to GND is from -0.6 to +7 V; (3): VPP (programming supply voltage with respect to GND) is from -0.6 to +14 V; (4): VCC (supply voltage with respect to GND) is from -0.6 to +7 V; (5): ESD protection is >2000 V; (6): the industrial operating range is from -40 to +85.
