GENERAL DESCRIPTION
The PCA84C122 is a stand-alone microcontroller designed for use in remote control transmitters for a wide range of applications.
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 °C.
