Programming Time

See the following table for typical programming times for Flash and EEPROM.

Table 1. Programming Times
Symbol Typical Programming Time
Page Buffer Clear (PBC) Seven CLK_CPU cycles
Page Write (WP) 2 ms
Page Erase (ER) 2 ms
Page Erase-Write (ERWP) 4 ms
EEPROM Erase (EEER) 4 ms
Chip Erase with UPDI

50 ms (1)
30 ms (2)
Notes:
  1. 1.This is the typical chip erase time for devices with 4 KB of Flash.
  2. 2.This is the typical chip erase time for devices with 2 KB of Flash.
