FEATURES
· Single-chip programmable peripheral for microcontroller-based applications
· 256K to 1 Mbit of UV EPROM with the following features:
  - Configurable as 32, 64, or 128 K x 8; or as 16, 32, or 64 K x 16
  - Divided into eight equally-sized mappable blocks for optimized address mapping
  - As fast as 70 ns access time, which includes address decoding
· 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.
· 19 I/O pins that can be individually configured for :
  - Microcontroller I/O port expansion
  - Programmable Address decoder (PAD) I/O
  - Latched address output
  - Open-drain or CMOS output
· Two Programmable Arrays  (PAD A and PAD B) replace your PLD or decoder, and have the following features:
  - Up to 18 Inputs and 24 outputs
  - 40 Product terms (13 for PAD A and 27 for PAD B)
  - Ability to decode up to 1 MB of address without paging
· Microcontroller logic that eliminates the need for external “glue logic” has the following features:
  - Ability to interface to multiplexed and non-multiplexed buses
  - Built-in address latches for multiplexed address/data bus
  - ALE and Reset polarity are programmable (Reset polarity not programmable on V-versions)
  - Multiple configurations are possible for interface to many different microcontrollers
· Optional built-in page logic expands the MCU address space by up to 16 times
· Programmable power management with standby current as low as 1µA for low-voltage version
  - CMiser bit—programmable option to reduce AC power consumption in memory
  - Turbo Bit (ZPSD only)—programmable bit to reduce AC and DC power consumption in the PADs.
· Track Mode that allows other microcontrollers or host processors to share access to the local data bus
· Built-in security locks the device and PAD decoding configuration
· Wide Operating Voltage Range
  - V-versions: 2.7 to 5.5 volts
  - Others: 4.5 to 5.5 volts
· Available in a variety of packaging (44-pin PLDCC, CLDCC, TQFP, and PQFP)
· Simple, menu-driven software (PSDsoft) allows configuration and design entry on a PC.
