Key Features
J
Single-chip programmable peripheral for microcontroller-based applications
J
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
J
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.
J
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
J
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
J
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
J
Optional built-in page logic expands the MCU address space by up to 16 times
J
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.
J
Track Mode that allows other microcontrollers or host processors to share access to the
local data bus
J
Built-in security locks the device and PAD decoding configuration
J
Wide Operating Voltage Range
V-versions: 2.7 to 5.5 volts
Others: 4.5 to 5.5 volts
J
Available in a variety of packaging (44-pin PLDCC, CLDCC, TQFP, and PQFP)
J
Simple, menu-driven software (PSDsoft) allows configuration and design entry on a PC.
