29.5 Flash Memory Characteristics

29. Electrical Characteristics

29.5.1 SH7058S

Table 29.22 shows the flash memory characteristics.

Table 29.22 Flash Memory Characteristics

Conditions: VCC = PLLVCC = 3.3 V Â±0.3 V, PVCC1 = 5.0 V Â±0.5 V/3.3 V Â±0.3 V,

PVCC2 = 5.0 V Â±0.5 V, AVCC = 5.0 V Â±0.5 V, AVref = 4.5 V to AVCC,

VSS = PLLVSS = AVSS = 0 V, Ta = â40Â°C to 125Â°C.

When PVCC1 = 3.3 V Â±0.3 V, VCC = PVCC1.

When writing or erasing on-chip flash memory, Ta = â40Â°C to 85Â°C.

Notes: 1. Use the on-chip programming/erasing routine for programming/erasure.

2. When all 0 are programmed.

3. 128 Kbytes of block

4. The total reprogramming time (programming time + erasing time) is as follows.

20 s (typ), 35 s (reference value), 50 s (max)

However, 90% of the values are within the reference value.

5. tE distributes focusing on near the typ. value.
