1004D–09/01
Notes: 1. The speed grade refers to maximum clock rate when using an external crystal or external clock drive. The internal RC oscil-
lator has the same nominal clock frequency for all speed grades.
2. In AT90LS2343-1xx, the internal RC oscillator is selected as default MCU clock source (RCEN fuse is programmed) when
the device is shipped from Atmel. In AT90LS2343-4xx and AT90S2343-10xx, the default MCU clock source is the clock
input pin (RCEN fuse is unprogrammed). The fuse settings can be changed by high voltage serial programming.
