148 / 186 page  ST10F280 148/186 19.1 - Identification Registers The ST10F280 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: 118Xh IDMEM (F07Ah / 3Dh) 1 ESFR Reset Value: 3080h IDPROG (F078h / 3Ch) 1 ESFR Reset Value: 0040h Note : 1. All identification words are read only registers. 15 14 13 12 11 10 9876543210 MANUF 00001 R MANUF Manufacturer Identifier 020h: STMicroelectronics Manufacturer (JTAG worldwide normalisation). 15 14 13 12 11 10 9876543210 CHIPID REVID RR REVID Device Revision Identifier CHIPID Device Identifier 118h: ST10F280 identifier. 15 14 13 12 11 10 987654 3210 MEMTYP MEMSIZE RR MEMSIZE Internal Memory Size is calculated using the following formula: Size = 4 x [MEMSIZE] (in K Byte) 080h for ST10F280 (512K Byte) MEMTYP Internal Memory Type 3h for ST10F280 (Flash memory). 15 14 13 12 11 10 9876543210 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 ST10F280 (5V).
