Product Specification
8. Memory Programming
8.1 Overview
8.1.1 Description
The Z51F0410 MCU incorporates flash and data EEPROM memory to which a program can be
written, erased, and overwritten while mounted on the board. Also, data EEPROM can be
programmed or erased in user program.
Serial ISP modes and byte-parallel ROM writer mode are supported.
8.1.2 Features
• Flash Size : 4Kbytes
• Single power supply program and erase
• Command interface for fast program and erase operation
• Up to 10,000 program/erase cycles at typical voltage and temperature for flash memory
• Up to 100,000 program/erase cycles at typical voltage and temperature for data EEPROM
memory
• Security feature
8.2 Flash and EEPROM Control and status register
Registers to control Flash and Data EEPROM are Mode Register (FEMR), Control Register (FECR),
Status Register (FESR), Time Control Register (FETCR), Address Low Register (FEARL), Address
Middle Register (FEARM), address High Register (FEARH) and Data Register (FEDR). They are
mapped to SFR area and can be accessed only in programming mode.
