49 / 74 page  ST10F168 49/74 19.1 - Identification Registers The ST10F168 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, – Programming voltage description. IDMANUF (F07Eh / 3Fh) ESFR Description MANUF : Manufacturer Identifier - 020h: STmicroelectronics Manufacturer (JTAG worldwide normalisation). IDCHIP (F07Ch / 3Eh) ESFR Description REVID : Device Revision Identifier - 1h for the first step, 2h for the second step,... CHIPID : Device Identifier - 0A8h is the identifier of ST10F168. IDMEM (F07Ah / 3Dh) ESFR Description MEMSIZE : Internal Memory Size - 040h for ST10F168 (256K Bytes). Internal Memory size is 4 * <MEMSIZE> (in K Byte). MEMTYP : Internal Memory Type - 3h for ST10F168 (Flash memory). IDPROG (F078h / 3Ch) ESFR Description PROGVDD : Programming VDD Voltage VDD voltage when programming EPROM or Flash devices is calculated using the follow- ing formula: VDD = 20 * <PROGVDD> / 256 [V] - 40h for ST10F168 (5V). PROGVPP : Programming VPP Voltage VPP voltage when programming EPROM or Flash devices is calculated using the follow- ing formula: VPP = 20 * <PROGVDD> / 256 [V] - 9Ah for ST10F168 (12V). 15 14 13 12 11 10 9876543210 MANUF ----- R 15 14 13 12 11 10 9876543210 CHIPID REVID RR 15 14 13 12 11 10 987654 3210 MEMTYP MEMSIZE RR 15 14 13 12 11 10 9876543210 PROGVPP PROGVDD RR |
