Introduction
Programmable Peripheral
PSD4XX Famly
Field-Programmable Microcontroller Peripherals
The PSD4XX family is a microcontroller peripheral that integrates high-performance and
user-configurable blocks of EPROM, programmable logic, and SRAM into one part.
The PSD4XX products also provide a powerful microcontroller interface that eliminates the
need for external “glue logic”. The no “glue logic” concept provides a user-programmable
interface to a variety of 8- and 16-bit (multiplexed or non-multiplexed) microcontrollers that
is easy to use. The part’s integration, small form factor, low power consumption, and ease
of use make it the ideal part for interfacing to virtually any microcontroller.
The PSD4XX provides two Zero-power PLDs (ZPLD): a Decode PLD (DPLD) and a
General-purpose PLD (GPLD). A configuration bit (Turbo) can be set by the MCU, and will
automatically place the ZPLDs into Standby Mode if no inputs are changing. The ZPLDs are
designed to consume minimum power using Zero-power CMOS technology that uses only
10 μA (typical) standby current. Unused product terms are automatically disabled, also
reducing power, regardless of the Turbo bit setting.
The main function of the DPLD is to perform address decoding for the internal I/O ports,
EPROM, and SRAM. The address decoding can be based on up to 24 bits of address
inputs, control signals (RD, WR, PSEN, etc.), and internal page logic. The DPLD supports
separate program and data spaces (for 8031 compatible MCUs).
The General-purpose PLD (GPLD) can be used to implement various logic functions
defined by the user, such as:
State machines
Loadable counters and shift registers
Inter-processor mailbox
External control logic (chip selects, output enables, etc.).
The GPLD has access to up to 59 inputs, 118 product terms, 24 macrocells, and 24 I/O
pins.
