10.4 Flash Memory Characteristics
10.5 External Clock Operation Timing
Freescale Semiconductor
Preliminary
1. There is additional overhead which is part of the programming sequence. See the 56F8300 Peripheral User Manual
2. Specifies page erase time. There are 512 bytes per page in the Data and Boot Flash memories. The Program Flash
1. Parameters listed are guaranteed by design.
2. See
3. The high or low pulse width must be no smaller than 8.0ns or the chip will not function.
4. External clock input rise time is measured from 10% to 90%.
5. External clock input fall time is measured from 90% to 10%.

for details. Program time is per 16-bit word in Flash memory. Two words at a time can be programmed within the Pro-
gram Flash module, as it contains two interleaved memories.
module uses two interleaved Flash memories, increasing the effective page size to 1024 bytes.
