uPSD34xx - SUMMARY DESCRIPTION
SUMMARY DESCRIPTION
The Turbo Plus uPSD34xx Series combines a
powerful 8051-based microcontroller with a flexi-
ble memory structure, programmable logic, and a
rich peripheral mix to form an ideal embedded
controller. At its core is a fast 4-cycle 8032 MCU
with a 4-byte instruction prefetch queue (PFQ) and
a 4-entry fully associative branching cache (BC).
The MCU is connected to a 16-bit internal instruc-
tion path to maximize performance, enabling loops
of code in smaller localities to execute extremely
fast. The 16-bit wide instruction path in the Turbo
Plus Series allows double-byte instructions to be
fetched from memory in a single memory cycle.
This keeps the average performance near its peak
performance (peak performance for 5V, 40MHz
Turbo Plus uPSD34xx is 10 MIPS for single-byte
instructions, and average performance will be ap-
proximately 9 MIPS for mix of single- and multi-
byte instructions).
USB 2.0 (full speed, 12Mbps) is included, provid-
ing 10 endpoints, each with its own 64-byte FIFO
to maintain high data throughput. Endpoint 0 (Con-
trol Endpoint) uses two of the 10 endpoints for In
and Out directions, the remaining eight endpoints
may be allocated in any mix to either type of trans-
fers: Bulk or Interrupt.
Code development is easily managed without a
hardware In-Circuit Emulator by using the serial
JTAG debug interface. JTAG is also used for In-
System Programming (ISP) in as little as 10 sec-
onds, perfect for manufacturing and lab develop-
ment. The 8032 core is coupled to Programmable
System 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 uPSD34xx also includes supervisor functions
such as a programmable watchdog timer and low-
voltage reset.

uPSD34xx devices, please refer to IMPORTANT
NOTES, page 262.
