W541L260
⢠Five types of interrupts
â Four internal interrupts (Divider 0, Divider 1, Timer 0, Timer 1)
â One external interrupt (Port RC)
⢠LCD driver output
â 32 segment à 4 common
â Static, 1/2 duty (1/2 bias), 1/3 duty (1/2 or 1/3 bias), 1/4 duty (1/3 bias) driving mode can be
selected
â LCD driver output pins can be used as DC output ports; selectable by code option
⢠MFP output pin
â Output is software selectable as modulating or nonmodulating frequency
â Works as frequency output specified by Timer 1
⢠Two built-in 14-bit clock frequency divider circuit (divider 0 and divider 1)
⢠Two built-in 8-bit programmable countdown timers
â Timer 0: one of two internal clock frequencies (FOSC/4 or FOSC/1024) can be selected
â Timer 1: includes an auto-reload function; and one of two internal clock frequencies (FOSC or
FOSC/64) can be selected or falling edge of pin RC.0 can be selected (output through MFP pin)
⢠Built-in 18/14-bit watchdog timer selectable for system reset
⢠Powerful instruction set: 115 instructions
⢠8-level subroutine (include interrupt) nesting
⢠Up to 4 μS instruction cycle (with 1 MHz operating frequency)
⢠Packaged in 80-pin QFP
