GENERAL DESCRIPTION
The CXLC8L048 is an 8-bit single chip micro-controller, it is one of CXLC8 series products. Its memory capacity includes 48 Bytes RAM, 1K *14 bits ROM. Other features include RTC timer, TCC timer, one Group Port I/O (8 I/O pins), a programmable sound generator (PJTMS) and a LCD module are built in the chip. The LCD module is capable of driving up to 12 segments and up to 4 commons and it supports 1/3 bias and 1/4 duty only (48 dots = 4com* 12seg).

—32768Hz crystal oscillator is available only.
lWhen 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 and 32768Hz clock turn on, RC oscillator turn off.
- Sleep: MCU and 32768Hz clock turn off, RC oscillator turn off.
- Idle: MCU turn off, 32768Hz clock turn on, RC oscillator turn off.
lWhen RC oscillator is available only, MCU supports three work modes to reduce the current consumer.
- Normal: MCU and RC oscillator turn on.
- Idle: MCU turn off, RC oscillator turn on.
- Sleep: MCU and RC oscillator turn off.
lWhen 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.
l1 hard interrupt source: RTC overflow interrupt.
lBuilt-in programmable sound generator (PJTMS).
lWatchdog Timer (WDT) with its own on-chip RC oscillator to prevent system stand still.
lBuilt-in power on reset (POR).
lOscillator Start-up Timer (OST).
lCMOS technology for low power consumption.
LCD Module Features
