27.5 Flash Memory Characteristics
Table 27.20 shows the flash memory characteristics.
Table 27.20 Flash Memory Characteristics
Conditions: VCC = PLLVCC = 3.3 V ±0.3 V, PVCC1 = 5.0 V ±0.5 V/3.3 V ±0.3 V,
PVCC2 = 5.0 V ±0.5 V, AVCC = 5.0 V ±0.5 V, AVref = 4.5 V to AVCC,
VSS = PLLVSS = AVSS = 0 V, Ta = –40°C to 125°C.
When PVCC1 = 3.3 V ±0.3 V, VCC = PVCC1.
When writing or erasing on-chip flash memory, Ta = –40°C to 85°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.
40 s (typ.), reference value: 60 s, 80 s (max.)
However, 90% of the values are within the reference value.
5. tP, tE distributes focusing on near the typ. value.
