SUMMARY DESCRIPTION
The PSD 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 SUMMARY
PSD provides an integrated solution to 16-bit MCU-based applications that includes configurable memories, PLD logic, and I/O:
■ Dual bank Flash memories
– 8Mbits of Primary Flash Memory (16 uniform sectors, 64Kbyte)
– 512Kbits of Secondary Flash Memory with 4 sectors
– Concurrent operation: READ from one memory while erasing and writing the other
■ 256Kbits of SRAM (battery-backed)
■ 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 l/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 fullchip 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
– 3V (+20/–10)
■ Memory Speed
– 100ns Flash memory and SRAM access time for VCC = 3V (+20/–10)
– 90ns Flash memory and SRAM access time for VCC = 3.3V (+/–10)
