STMicroelectronics Introduces 10-MIPs 8-bit MCU with Full-Speed USB 2.0.
Tuesday February 22, 6:00 am ET

GENEVA, Feb. 22 /PRNewswire-FirstCall/ -- STMicroelectronics (NYSE: STM - News) today introduced the uPSD3400 Turbo Plus series of its popular uPSD family. uPSD is a family of 8051-class embedded flash microcontrollers that offers system-level-integration with world-leading Flash and SRAM densities (up to 256-kbytes and 32-kbytes, respectively) for general-purpose 8-bit embedded applications. The uPSD3400 Turbo Plus series performs up to 10 MIPS peak and provides full speed USB.

The new uPSD3400 Turbo Plus series is suitable for a wide range of embedded applications, particularly those requiring the high amount of memory offered by the family. Examples of these applications include industrial controls and point-of-sale peripherals, such as terminals, thermal printers, barcode scanners, and card readers.

The core of the uPSD3400 Turbo Plus series is a 4-cycle-per-instruction 40-MHz 8032 MCU. This high-performance core is further enhanced by the addition of an internal 16-bit path that allows 2-byte instructions to be fetched in a single memory cycle. The wider path coupled with a pre-fetch queue and branch cache brings average performance to 9 MIPS, with peak performance at 10 MIPS.

The uPSD3400 Turbo Plus series supports USB 2.0 at full-speed (12-Mbps). The USB provides 10 endpoint pairs (in/out), each with its own 64-byte FIFO including support for Control, Interrupt, and Bulk transfers.

A JTAG interface supports in-system programming and MCU core debug with high speed instruction tracing capability, eliminating the need for a hardware In-Circuit Emulator (ICE).

Based on ST's proprietary Programmable System Device (PSD) architecture, uPSD3400 devices feature dual independent banks of Flash memory, 8 kbytes of SRAM, and over 3000 gates of programmable logic with 16 macrocells. The dual-bank Flash architecture and programmable decode logic support true READ-while-WRITE concurrent access for In-Application Programming (IAP). Memory mapping is handled by an integrated decoding PLD that can assign any Flash or SRAM memory segment to any address on any memory page or bank. Additionally, Flash memory can be allocated to 8032-code space or data space in almost any proportion as needed, which is a feature unique to uPSD devices.

Other peripherals include a 16-bit Programmable Counter Array (PCA), an 8-channel 10-bit resolution analog-to-digital converter, SPI and IrDA interfaces, six PWM (pulse-width modulated) channels, an I2C (Intelligent Interface Controller) master/slave bus controller, two standard UARTs (Universal Asynchronous Receiver/Transmitter), supervisory functions such as a watchdog timer and low-voltage detect, and up to 45 general-purpose I/O pins.

Designers can use the 16-macrocell CPLD to replace external glue logic devices such as 22V10 PLDs, 20L8 PALs, and 74-series discrete logic ICs. Common functions forged from the CPLD array include state machines, shifters and counters, keypad and control panel interfaces, chip-selects for external devices, clock dividers, multiplexers, and handshake delay circuits. uPSD3400 devices are sampling now with volume production planned for late 1Q 2005 in 52-pin and 80-pin TQFP packages, with industrial operating temperature -40C to +85C at 5.0V and 3.3V. Pricing starts at $4.00 in quantities of 10,000.
