Note 1: Data in “Typical” column is at 3.3V, 25°C unless otherwise stated.

2: The minimum SYSCLK for row programming is 4 MHz. Care should be taken to minimize bus activities

during row programming, such as suspending any memory-to-memory DMA operations. If heavy bus loads

are expected, selecting Bus Matrix Arbitration mode 2 (rotating priority) may be necessary. The default

Arbitration mode is mode 1 (CPU has lowest priority).

3: Refer to the “PIC32 Flash Programming Specification” (DS61145) for operating conditions during

programming and erase cycles.
