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