72 / 116 page ![]() Electrical characteristics STM8AF6388 72/116 DocID031156 Rev 1 10.3.5 Memory characteristics Flash program memory/data EEPROM memory General conditions: TA = -40 °C to 150 °C. Table 33. Flash program memory/data EEPROM memory Symbol Parameter Conditions Min(1) 1. Guaranteed by characterization results, not tested in production. Typ Max Unit VDD Operating voltage (all modes, execution/write/erase) fCPU is 16 to 24 MHz with 1 ws fCPU is 0 to 16 MHz with 0 ws 3.0 - 5.5 V VDD Operating voltage (code execution) fCPU is 16 to 24 MHz with 1 ws fCPU is 0 to 16 MHz with 0 ws 2.6 - 5.5 tprog Standard programming time (including erase) for byte/word/block (1 byte/4 bytes/128 bytes) -- 6 6.6 ms Fast programming time for 1 block (128 bytes) -- 3 3.3 terase Erase time for 1 block (128 bytes) - - 3 3.3 Table 34. Flash program memory Symbol Parameter Condition Min Max Unit TWE Temperature for writing and erasing - -40 150 °C NWE Flash program memory endurance (erase/write cycles)(1) 1. The physical granularity of the memory is four bytes, so cycling is performed on four bytes even when a write/erase operation addresses a single byte. TA = 25 °C 1000 - cycles tRET Data retention time TA = 25 °C 40 - years TA = 55 °C 20 - |
