Summary description
The PSD8XXFX family of memory systems for microcontrollers (MCUs) brings in-system-programmability (ISP) to Flash memory and programmable logic. The result is a simple and flexible solution for embedded designs. PSD devices combine many of the peripheral functions found in MCU based applications.
Features
â Flash in-system programmable (ISP) peripheral for 8-bit MCUs
â Dual bank Flash memories
â Up to 2 Mbit of primary Flash memory (8 uniform sectors, 32K x8)
â Up to 256 Kbit secondary Flash memory (4 uniform sectors)
â Concurrent operation: read from one memory while erasing and writing the other
â Up to 256 Kbit SRAM
â 27 reconfigurable I/Oports
â Enhanced JTAG serial port
â PLD with macrocells
â Over 3000 gates of PLD: CPLD and DPLD
â CPLD with 16 output macrocells (OMCs) and 24 input macrocells (IMCs)
â DPLD - user defined internal chip select decoding
â 27 individually configurable I/O port pins
They can be used for the following functions:
â MCU I/Os
â PLD I/Os
â Latched MCU address output
â Special function I/Os.
â 16 of the I/O ports may be configured as open-drain outputs.
â In-system programming (ISP) with JTAG
â Built-in JTAG compliant serial port allows full-chip in-system programmability
â Efficient manufacturing allow easy product testing and programming
â Use low cost FlashLINK cable with PC
â Page register
â Internal page register that can be used to expand the microcontroller address space by a factor of 256
â Programmable power management
â Packages are ECOPACK®
