GENERAL DESCRIPTION
The CXLC8L050 is an 8-bit single chip micro-controller, it is one of CXLC8L050 series products. Its memory capacity includes 80 Bytes SRAM, 2K *14 bits ROM. Other features include RTC timer, TCC timer, two Groups Port I/O (I/O pins: P1.0~P1.3, P2.0~P2.4, P2.6), a programmable sound generator (PJTMS) and a LCD module are built in the chip. The LCD module is capable of driving up to 24 segments and up to 4 commons and it supports 1/3 bias (96 dots = 4com* 24seg)
FEATURES
Microcontroller Features
l Typical operating voltage: 1.5V or 3V.
l Operating frequency up to 500KHz(An instruction cycle equals to 2 oscillator periods).
l 2K*14 Bits mask ROM.
l 80 Bytes SRAM.
l 2 Groups GPIO: P1.0~P1.3, P2.0~P2.4, P2.6.
l 4 level stacks for subroutine nesting.
l Clock Sources
－ 32768Hz crystal oscillator with external crystal. － RC oscillator with external resistor.
l Oscillator mode
－ 32768Hz crystal oscillator work only. － 32768Hz crystal oscillator and RC oscillator work together.
l When 32768Hz crystal oscillator and RC oscillator work together, MCU supports five work modes to reduce the current consumer.
－ Normal1: MCU, 32768Hz clock and RC oscillator turn on.
－ Normal2: MCU, RC oscillator turn on, 32768Hz clock turn off.
－ Slow: MCU, 32768Hz clock turn on, RC oscillator turn off.
－ Idle: MCU, RC oscillator turn off, 32768Hz clock turn on.
－ Sleep: MCU, 32768Hz clock and RC oscillator turn off.
l When 32768Hz crystal oscillator work only, MCU supports three work modes to reduce the current consumer.
－ Slow: MCU and 32768Hz crystal oscillator turn on.
－ Idle: MCU turn off, 32768Hz crystal oscillator turn on.
－ Sleep: MCU and 32768Hz crystal oscillator turn off.
l 6 hard interrupt source: RTC overflow interrupt, 4 external interrupts, TCC overflow interrupt.
l Built-in programmable sound generator (PJTMS).
l Watchdog Timer (WDT) with its own on-chip RC oscillator to prevent system stand still.
l Built-in power on reset (POR).
l Oscillator Start-up Timer (OST).
l CMOS technology for low power consumption.
LCD Module Features
l Typical operation voltage: 3V.
l LCD operation current:
－ Stand by current: < 1uA
－ Start up current: < 10mA
l 96(4*24) dots (1/3 bias).
