uPSD3422E 具有可编程逻辑和USB的uPSD3400系列8032微控制器

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.
