Description
碌PD789881
Ultra-Low-Power 8-Bit Microcontroller
with LCD Controller
The 碌PD789881 is ideal for-battery-powered applications as it was designed for ultra-low
power consumption of 18 碌A(chǔ) at 2.7 volts during normal operation and 0.9 碌A(chǔ) in STOP
mode. It also has an LCD controller that can directly drive 104 LCD segments.
A built-in 500 kHz on-chip oscillator drives the CPU clock, while all peripherals operate
from an external 32 kHz clock. Users can dynamically switch between the two clock
speeds to accomodate the performance and power consumption requirements for
their applications.
The product鈥檚 extensive tool chain contains a software simulator, C compiler, relocatable
assembler, debugger, and in-circuit emulator. Programming examples for the on-chip
peripherals can be found in the microcontroller section of www.necel.com.
