 Programming and erase can be done over the full operation voltage range

 Write, read and erase operation are all supported by In-Circuit Programming (ICP)

 Support overall/sector erase and programming

 Minimum program/erase cycles: Program area: 10000

EEPROM-like area: 100,000

 Minimum years data retention: 10

 Low power consumption

The SH79F3283 embeds 32K flash program memory for program code. The flash program memory provides electrical

erasure and programming and supports In-Circuit Programming (ICP) mode and Self-Sector Programming (SSP) mode. Every

sector is 1024 bytes.

The SH79F3283 also embeds 1024 bytes EEPROM-like memory block for storing user data. Every sector is 256 bytes. It has

4 sectors.

Flash operation defined:

In-Circuit Programming (ICP): Through the Flash programmer to wipe the Flash memory, read and write operations.

Self-Sector Programming (SSP) mode: User Program code run in Program Memory to wipe the flash memory, read and write

operations.

Flash Memory Supports the Following Operations:

(1) Code Protection Control Mode

SH79F3283 code protection function provides a high-performance security measures for the user. Each partition has four

modes are available.

Code protection mode 0: allow/forbid any programmer write/read operations (not including overall erasure).

Code protection mode 1: allow/forbid through MOVC instructions to read operation in other sectors, or through SSP mode to

erased/write operation.

Code-protect control mode 2: Used to enable/disable the erase/write EEPROM operation through SSP Function.

Code-protect control mode 3: Customer password, write by customer, consists of 6 bytes. To enable the wanted protect mode,

the user must use the Flash Programmer to set the corresponding protect bit.

The user must use the following two ways to complete code protection control mode Settings:

1. Flash programmer in ICP mode is set to corresponding protection bit to enter the protected mode.

2. The SSP mode does not support code protection control mode programming.
