ST10F269
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-
IDMANUF (F07Eh / 3Fh)
IDCHIP (F07Ch / 3Eh)
IDMEM (F07Ah / 3Dh)
IDPROG (F078h / 3Ch)
Note : 1. All identification words are read only registers.

Device Revision Identifier
Device Identifier - 10Dh: ST10F269 identifier.
Internal Memory Size is calculated using the following formula:
Size = 4 x [MEMSIZE] (in K Byte) - 040h for ST10F269 (256K Byte)
Internal Memory Type - 3h for ST10F269 (Flash memory).

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.
