DescriptionSTMicrosystems PSD854F2 Flash in-system programmable (ISP) | Peripherals for 8-bit MCUs, 5 V | Complex Programmable Logic Devices (CPLD)
Key FeaturesFlash 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
