20 - SPECIAL FUNCTION REGISTER OVERVIEW

131/184

20.1 - Identification Registers

The ST10F269 has four Identification registers,

mapped in ESFR space. These registers contain:

– A manufacturer identifier,

– A chip identifier, with its revision,

– A internal memory and size identifier and pro-

gramming voltage description.

Note: 256K and 128K versions of ST10F269 have

the same IDMEM corresponding to 256K.

Both versions are based on the same device with

the only difference that the two upper banks of

Flash are not tested on 128K versions. Therefore,

there is no way to detect by software if a device is

a 128K version or a 256K version.

PROGVPP

PROGVDD

Programming VDD Voltage

VDD voltage when programming EPROM or FLASH devices is calculated using the

following formula: VDD = 20 x [PROGVDD] / 256 (volts) - 40h for ST10F269 (5V).

PROGVPP

Programming VPP Voltage (no need of external VPP) - 00h
