WT5080 Product details

DESCRIPTION
The WT5080 is a high-performance, low-cost, CMOS 8-bit single-chip microcontroller with 48x32/64x32 dot-matrix LCD driver, which is suitable for variable applications, especially when large number of LCD dots and large ROM space are needed, including edutainment toys, speech synthesizer, Chinese character pagers, databank, handheld games and talking devices.
This chip has 8-bit CPU, RAM, I/Os, dual 16-bit timer/counters, interrupt controller, and a 9-bit push-pull D/A output. To be suitable for portable battery-powered applications, a power saving function is included.

FEATURES
◆ 8-bit single chip microcontroller with 48x32/64x32 LCD driver
◆ 6.448Kbytes SRAM and 512 Kbytes ROM
◆ Voltage operating range from 2.9 V to 3.2 V
◆ Built-in crystal OSC circuit and RC oscillator with maximum frequency up to 3.0 MHz
◆ 5 interrupt sources (external:1; internal:4) ; all sources have independent latches each and multiple interrupt control is available
◆ I/O port (20 pins)
    。 I/O port 4 pins
    。 I/O port 16 pins
◆ Watchdog Timer
◆ Operating current 1mA/2MHz@3V; key wake-up mode is provided
◆ RC OSC OFF and 32.768KHz X’tal ON (LCD Panel OFF): current consumption < 15 uA @3V
    NOTE: LCD panel can be turned off, but 32.768KHz crystal is always ON
◆ Dual 16-bit timer/counters
◆ 9-bit push-pull D/A converter
◆ Package: Chip form or 128-pin LQFP (14mm x 14mm x 1.4mm)
