123 / 161 page  ST10F269Z2Qx 123/161 20.1 - Identification Registers The ST10F269Z2Qx has four Identification registers, mapped in ESFR space. These register contain: – A manufacturer identifier, – A chip identifier, with its revision, – A internal memory and size identifier and programming voltage description. IDMANUF (F07Eh / 3Fh) 1 ESFR Reset Value: 0401h IDCHIP (F07Ch / 3Eh) 1 ESFR Reset Value: 10DXh IDMEM (F07Ah / 3Dh) 1 ESFR Reset Value: 3040h IDPROG (F078h / 3Ch) 1 ESFR Reset Value: 0040h Note : 1. All identification words are read only registers. 15 14 13 12 11 10 987654 3210 MANUF 0 0001 R MANUF Manufacturer Identifier - 020h: STMicroelectronics Manufacturer (JTAG worldwide normalization). 15 14 13 12 11 10 987654 3210 CHIPID REVID RR REVID Device Revision Identifier CHIPID Device Identifier - 10Dh: ST10F269Z2Qx identifier. 15 14 13 12 11 10 9876543210 MEMTYP MEMSIZE RR MEMSIZE Internal Memory Size is calculated using the following formula: Size = 4 x [MEMSIZE] (in K Byte) - 040h for ST10F269Z2Qx (256K Byte) MEMTYP Internal Memory Type - 3h for ST10F269Z2Qx (Flash memory). 15 14 13 12 11 10 987654 3210 PROGVPP PROGVDD RR 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 ST10F269Z2Qx (5V). PROGVPP Programming VPP Voltage (no need of external VPP) - 00h |
