The PMS152 family is an IO-Type, fully static, OTP-based CMOS 8-bit microcontroller. It employs RISC architecture and all the instructions are executed in one cycle except that some instructions are two cycles that handle indirect memory access.

Special Features :

General purpose series
Please don’t apply to AC RC step-down powered, high power ripple or high EFT requirement application
Operating temperature range: -20°C ~ 70°C

System Features :

1.25KW OTP program memory
80 Bytes data RAM
One hardware 16-bit timer
One hardware 8-bit timers with 6/7/8-bit PWM generation
One set triple 11bit SuLED (Super LED) PWM generators and timers
One hardware comparator
14 IO pins with optional pull-high resistor
Three different IO Driving capability group to meet different application requirements
- PB3, PB5, PB7 Drive/ Sink Current= 5mA/30mA
- Other IOs (except PA5) Drive/ Sink Current = 5mA/10mA
- PA5 Sink Current = 10mA
Every IO pin can be configured to enable wake-up function
Clock sources: IHRC, ILRC & EOSC(XTAL mode, Reserved1)
For every wake-up enabled IO, two optional wake-up speed are supported: normal and fast
Eight levels of LVR: 4.5V, 3.5V, 3.0V, 2.75V, 2.5V, 2.2V, 2.0V and 1.8V
Two selectable external interrupt pins: PA0/PB5, PB0/PA4
Band-gap circuit to provide 1.20V reference voltage
