HMS87C5216
CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
FOR UR(Universal Remocon) & WIRELESS KEYBOARD
1. OVERVIEW
1.1 Description
The HMS87C5216 is an advanced CMOS 8-bit microcontroller with 16K bytes of ROM. The device is one of GMS800 family. The Mag-
naChip Semicon HMS87C5216 is a powerful microcontroller which provides a highly flexible and cost effective solution to many UR &
Keyboard applications. The HMS87C5216 provides the following standard features: 16K bytes of ROM, 320 bytes of RAM, 8-bit timer/
counter, on-chip oscillator,clock circuitry and RC wake up function. 4 chanel ADC, In addition, the HMS87C5216 Series supports power
saving modes to reduce power consumption
