SPCP758A
Low Power MCU with MTP and DC-to-DC Converter

General Description

SPCP758A is a new Highly-integrated MCU for Wireless Application developed by SunplusIT. The chip contains an 8-bit SUNPLUSIT CPU core with two timers, Timer0 and Timer1. Memory includes 8K bytes of MTP (Multi-Time-Programmable) Memory with 256 bytes of RAM (including stack buffers). The SPCP758A further features a built-in DC/DC which can support one battery applications and is especially suitable for 2.4G RF Mice and many other battery-base appliances.

Features

• CPU
  • Built-in 8-bit SUNPLUSIT CPU core with the maximum clock rate to be 12MHz
• Memory
  • 8K bytes MTP (Multi-Time-Programmable) Memory and 256 bytes RAM
  • Option bytes located in the MTP Memory are loaded before Power-On Reset
• Power
  • Built-in DC/DC and LDO converters which can supply up to 40mA current (Vout1 + Vout2) for external devices and on-chip power consumption
  • The built-in wide operating range DC/DC allows either single battery or two-battery in serial applications.
• Clock
  • Built-in 12MHz Oscillator (osc12m), the system clock which is derived from it and can be further divided to a slower rate.
  • Built-in 5KHz R-Oscillator (R-OSC) for low power application usage.
• I/O
  • Up to 25 GPIOs available on QFN32 package
  • Programmable I/O direction with resistive pull-up/down control
• Timer
  • One 14-bit free-running timer with overflow interrupt and real time interrupt
  • One 8-bit re-loadable timer can be cascaded as a 16-bit timer
• Input capture
  • Two input capture registers
  • Selectable edge triggering for capture input
  • Pulse or period measurement
