LPC82x
32-bit ARM Cortex-M0+ microcontroller
12. Dynamic characteristics
12.1 Flash/EEPROM memory
[1] Number of program/erase cycles.
[2] Programming times are given for writing 64 bytes to the flash. T
amb
<= +85 C. Flash programming with IAP
calls (see LPC82x user manual).
12.2 External clock for the oscillator in slave mode
Remark: The input voltage on the XTALIN and XTALOUT pins must be  1.95 V (see
Table 8
). For connecting the oscillator to the XTAL pins, also see Section 12.2.
Conditions: V
DD
= 1.8 V; standard port pins. Conditions: V
