PCA84C622 Features
` 84CXXX CPU
` ROM, RAM and I/O configurations are device dependent; see Chapter 3
` Two test inputs: T0 (ANDed with Port 1 input lines) and T1
` 3 single-level vectored interrupt sources:
external (T0/INT and Port 1, for keypad press wake-up function)
timer/counter (TI)
hardware modulator interrupt
` 8-bit programmable timer/counter with 5-bit pre-scaler
` Power saving: Idle and Stop modes are provided
` Hardware Modulator providing pulse bursts, with:
programmable duty factor for each pulse
programmable number of pulses
` One output line from the Hardware Modulator to control the driver transistor for the infrared LED (IR-LED). Capable of sinking 27 mA at VDD = 2.0 V, VOUT = 1.0 V
` Watchdog Timer to keep the transmitter from being locked or malfunction
` Available packages: SO and DIP types (SO20, SO24, SO28, SDIP24 and DIP20); see Chapter 4
` On-chip oscillator: 455 kHz to 6 MHz
` Single supply voltage: 2.0 V to 5.5 V
` Operating temperature: -20 to +50 .
