1. GENERAL DESCRIPTION
The GPM8F3132A  is a highly  integrated microcontroller. Besides integrating  a  pipelined  1T 8051  CPU,  1K-byte  XRAM,  256Byte IDM  SRAM  and  32K  Byte  program  Flash,  it  also  includes  34 programmable  multi-functional  I/Os,  Timer0/1/2,  UARTs,  SPI  (master),  Motor  control  unit  with  built-in  OP  and  comparators,  audio and one up to 8 channel of 12-bit ADC for general-purpose  application.  It operates over a wide voltage  range of 2.4V  - 5.5V  with different  clock  sources.  It  has  three  modes  in  power  management  unit.  There  is  also  one  on  chip  debug  circuit  with  two  pins  to  facilitate  full  speed  in-system  debug.  The  detail  are  described in the following sections

你好，朋友，请问你的GPM8F3132A的电机驱动电路图还保留吗？能发给我吗？刚买了一个电动滑板马达控制器，但是没有可以参考的图，那个电路是这个单片机上控制的，感激不尽。383158083@qq.com
