uPSD32xx
SUMMARY DESCRIPTION
The uPSD32xx Series combines a fast 8051- Dual Flash memory banks provide a robust solu-
based microcontroller with a flexible memory tion for remote product updates in the field through
structure, programmable logic, and a rich periph- In-Application Programming (IAP). Dual Flash
eral mix including USB, to form an ideal embedded banks also support EEPROM emulation, eliminat-
controller. At its core is an industry-standard 8032 ing the need for external EEPROM chips.
MCU operating up to 40MHz.
General purpose programmable logic (PLD) is in-
A JTAG serial interface is used for In-System Pro- cluded to build an endless variety of glue-logic,
gramming (ISP) in as little as 10 seconds, perfect saving external logic devices. The PLD is config-
for manufacturing and lab development.

The USB 1.1 low-speed interface has one Control
endpoint and two Interrupt endpoints suitable for
soft Express, available from the web at

HID class drivers.
The 8032 core is coupled to Programmable Sys-
t(s) ^{tem Device (PSD) architecture to optimize the}
8032 memory structure, offering two independent
c banks of Flash memory that can be placed at vir-
u tually any address within 8032 program or data ad-
d _{dress space, and easily paged beyond 64K bytes}
ro ^{using on-chip programmable decode logic.}
The uPSD32xx also includes supervisor functions
such as a programmable watchdog timer and low-
voltage reset.
