Product Features

1.1. Special Features

 In applications with AC RC step-down power supply or high EFT requirements, the system circuit needs to be modified if necessary to improve the anti-interference capability

 Operating temperature range: -40°C ~ 85°C

1.2. System Features

 2KW MTP program memory (programming cycle at least 1,000 times)

 128 Bytes data RAM

 One hardware 16-bit timer

 Two hardware 8-bit timer with PWM generators

 Three hardware 11-bit PWM generators

 Provide one hardware comparator

 14 IO pins with optional pull-high resistor

 Three different IO driving capability groups to meet different application requirement

 Optional IO driving capability for each port：normal drive and low drive

 Every IO pin can be configured to enable wake-up function

 Built-in VDD/2 bias voltage generator to provide maximum 4x9 dots LCD display

 Clock sources: IHRC, ILRC & EOSC(XTAL mode)

 For every wake-up enabled IO, two optional wake-up speed are supported: normal and fast

 Eight levels of LVR: 4.0V, 3.5V, 3.0V, 2.75V, 2.5V, 2.2V, 2.0V, 1.8V

 Two external interrupt pins

1.3. CPU Features
