80 / 124 page ![]() Electrical parameters STM8AL313x/4x/6x STM8AL3L4x/6x 80/124 DocID18474 Rev 7 9.3.5 Memory characteristics TA = -40 to 125 °C unless otherwise specified. Flash memory Table 36. RAM and hardware registers Symbol Parameter Conditions Min Typ Max Unit VRM Data retention mode (1) Halt mode (or Reset) 1.65 - - V 1. Minimum supply voltage without losing data stored in RAM (in Halt mode or under Reset) or in hardware registers (only in Halt mode). Guaranteed by characterization, not tested in production. Table 37. Flash program memory/data EEPROM memory Symbol Parameter Conditions Min Typ Max Unit VDD Operating voltage (all modes, read/write/erase) fSYSCLK = 16 MHz 1.65 - 3.6 V tprog Programming time for 1 or 128 bytes (block) erase/write cycles (on programmed byte) -- 6 - ms Programming time for 1 to 128 bytes (block) write cycles (on erased byte) -- 3 - Iprog Programming/ erasing consumption TA=+25 °C, VDD = 3.0 V - 0.7 - mA TA=+25 °C, VDD = 1.8 V - - Table 38. Flash program memory Symbol Parameter Conditions Min Max Unit TWE Temperature for writing and erasing - -40 125 °C NWE Flash program memory endurance (erase/write cycles)(1) TA = 25 °C 1000 - cycles tRET Data retention time TA = 25 °C 40 - years TA = 55 °C 20 - 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. |
