Keil Supports ST µPSD3200 Devices

Dallas, TX: The µPSD3200 family of 8032-based microcontrollers is STMicroelectronics' first foray into the world of 8051-class microcontrollers. The new family features 8-bit microcontrollers with a 40MHz 8032-microcontroller core surrounded by dual banks of Flash memory, SRAM, programmable logic, I/O, and a wide variety of peripherals. With Flash and SRAM densities of up to 288 Kbytes and 32 Kbytes, respectively, the µPSD3200 family offers the largest Flash and SRAM densities available today in an 8051-class microcontroller, and the only one to include on-chip programmable logic.

Although C compilers and firmware development tools from any vendor that supports the standard 8051 architecture may be used for the µPSD, the Keil µVision IDE is the only one to directly support the µPSD. All C Code generated from ST's µPSD Development Software, PSDsoft Express, is directly compatible with the Keil PK51 and DK51 tool kits. The PK51 includes an excellent non-intrusive background debugger, ISD51, which uses either of the two UARTs on the µPSD for firmware debugging with breakpoints. For future µPSD devices, Keil will be the only compiler to support the dual-data pointers of the µPSD in such a way as to allow for more efficient code development, and JTAG debugging.

• Further information on the µPSD family of devices is available at www.st.com/micropsd.
• PSDsoft Express is free of charge and can be downloaded from ST's website at www.st.com/psd
