General Description and Block Diagram
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.

FEATUREs
Special Features
◆ General purpose series
◆ Not supposed to use in AC RC step-down powered or high EFT requirement applications.
   PADAUK assumes no liability if such kind of applications can not pass the safety regulation tests.
◆ 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
   (1) PB3, PB5, PB7 Drive/ Sink Current= 7mA/30mA
   (2) Other IOs (except PA5) Drive/ Sink Current = 7mA/14mA
   (3) PA5 Sink Current = 4mA
◆ Every IO pin can be configured to enable wake-up function
◆ 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: 4.5V, 3.5V, 3.0V, 2.7V, 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

CPU Features
◆ One processing unit operating mode
◆ 86 powerful instructions
◆ Most instructions are 1T execution cycle
◆ Programmable stack pointer to provide adjustable stack level
◆ Direct and indirect addressing modes for data access.
   Data memories are available for use as an index pointer
   of Indirect addressing mode
◆ IO space and memory space are independent
