The Turbo Plus uPSD34xx Series combines a powerful 8051-based

microcontroller with a

flexible 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 instruction 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 approximately 9 MIPS for mix of single- and

multi-byte

instructions).

USB 2.0 (full speed, 12Mbps) is included, providing 10 endpoints, each with

its own 64-byte

FIFO to maintain high data throughput. Endpoint 0 (Control 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 transfers: 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 seconds, perfect for manufacturing and lab development. 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

virtually any address

within 8032 program or data address space, and easily paged beyond 64K bytes

using onchip

programmable decode logic.

Dual Flash memory banks provide a robust solution for remote product updates

in the field

through In-Application Programming (IAP). Dual Flash banks also support

EEPROM

emulation, eliminating the need for external EEPROM chips.

General purpose programmable logic (PLD) is included to build an endless

variety of gluelogic,

saving external logic devices. The PLD is configured using the software

development

tool, PSDsoft 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.
