SUMMARY DESCRIPTION
The uPSD323x Series combines a fast 8051-
based microcontroller with a flexible memory
structure, programmable logic, and a rich periph-
eral mix including USB, to form an ideal embedded
controller. At its core is an industry-standard 8032
MCU operating up to 40MHz.
A JTAG serial interface is used for In-System Pro-
gramming (ISP) in as little as 10 seconds, perfect
for manufacturing and lab development.
The USB 1.1 low-speed interface has one Control
endpoint and two Interrupt endpoints suitable for
HID class drivers.
The 8032 core is coupled to Programmable Sys-
tem Device (PSD) architecture to optimize the
8032 memory structure, offering two independent
banks of Flash memory that can be placed at vir-
tually any address within 8032 program or data ad-
dress space, and easily paged beyond 64K bytes
using on-chip programmable decode logic.
Dual Flash memory banks provide a robust solu-
tion for remote product updates in the field through
In-Application Programming (IAP). Dual Flash
banks also support EEPROM emulation, eliminat-
ing the need for external EEPROM chips.
General purpose programmable logic (PLD) is in-
cluded to build an endless variety of glue-logic,
saving external logic devices. The PLD is config-
ured using the software development tool, PSD-
soft Express, available from the web at
www.st.com/psm
, at no charge.
The uPSD323x also includes supervisor functions
such as a programmable watchdog timer and low-
voltage reset.
