Flash memory characteristics
VDDQ = 2.7 - 3.6V, VDD = 1.65 - 2V, TA = -40 / 85 °C unless otherwise specified.
Table 15.
Flash memory program/erase characteristics
Notes: 1 STR91xFx44 devices have 512 Kbytes primary Flash, STR91xFx32 devices have 256 Kbytes
primary Flash
2VDD = 1.8V, VDDQ = 3.3V, TA = 25°C.
3 Flash read access for synchronous addresses is 96 MHz maximum.
4 Flash read access for asynchronous accesses requires 2 wait states when FMI clock is above
66 MHz. See STR91xF Flash Programming Manual for more information.
