VRM

Data retention mode(1)

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 design, not tested in production.

Halt mode (or reset)

VIT-max(2)

2. Refer to Section 10.3: Operating conditions for the value of VIT-max.

tprog

Standard programming time (including

erase) for byte/word/block



(1 byte/4 byte/128 byte)

6.6

Fast programming time for 1 block



(128 byte)

terase

Erase time for 1 block (128 byte)

NRW

Erase/write cycles



(program memory)(2)

2. The physical granularity of the memory is 4 byte, so cycling is performed on 4 byte even when a

write/erase operation addresses a single byte.

Data retention (program and data

memory) after 10k erase/write cycles

at TA= +55 °C

TRET = 55 °C
