TinyPowerTM A/D Type with LCD 8-Bit OTP MCU
General Description
These TinyPowerTM A/D Type with LCD 8-bit high performance RISC architecture microcontrollers
are specifically, designed for applications that interface directly to analog signals and which require
an LCD or LED interface. The devices include an integrated multi-channel Analog to Digital
Converter, Pulse Width Modulation outputs and an LCD/LED driver.
With their fully integrated SPI and I2C functions, designers are provided with a means of easy
communication with external peripheral hardware. The benefits of integrated A/D, LCD, and
PWM functions, in addition to low power consumption, high performance, I/O flexibility and
low-cost, provides the device with the versatility for a wide range of products in the home appliance
and industrial application areas. Some of these products could include electronic metering,
environmental monitoring, handheld instruments, electronically controlled tools, motor driving in
addition to many others.
The unique Holtek TinyPower technology also gives the devices extremely low current consumption
characteristics, an extremely important consideration in the present trend for low power battery
powered applications. The usual Holtek MCU features such as power down and wake-up functions,
oscillator options, programmable frequency divider, etc. combine to ensure user applications require
a minimum of external components.
