#107680 - Atmel parts Responding to: ???'s previous message |
Atmel produces
AT89C51RD2, AT89C51ED2, AT89C51ID2, AT89C51AC3, AT89C51CC03 and some others with 64kb of FLASH program memory. Look at Parametric Product Table and their datasheets. By the way, Atmel provides two different ways of ISP. One method is used for AT89Sxx derivatives and may be named "hardware ISP": MCU is put into reset state and then its memory is programmed via SPI-like interface. Other ISP derivatives (including listed in the beginning of the post) are programmed by "software ISP". With this way, MCU executes special part of software called "bootloader" which is factory- or user-programmed. Bootloader gets bytes to be programmed, via one of interfaces (UART, CAN, USB or others) then calls factory-programmed API which does program them into FLASH memory. Regards, Oleg |
