PSD4256G6V
Flash in-system programmable (ISP) peripherals
for 8-bit or 16-bit MCUs
Features
Dual bank Flash memories
– 8 Mbits of primary Flash memory (16
uniform sectors, 64 Kbytes)
– 512 Kbits of secondary Flash memory with
4 sectors
– Concurrent operation: read from one
memory while erasing and writing the other
– 256 kbits of SRAM
– 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
Seven I/O ports with 52 I/O pins
52 individually configurable I/O port pins that
can be used for the following functions:
– MCU I/Os
– PLD I/Os
– Latched MCU address output
– Special function I/Os
– l/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
High endurance
– 100,000 erase/write cycles of Flash
memory
– 1,000 erase/write cycles of PLD
– 15 year data retention
Single supply voltage
