GPC22F340A


Working Voltage (V)Max.CPU Speed (MHz)E-Flash (Byte)RAM (Byte)I/OAudio OutputHigh Sink I/OPWM I/OIR
2.0~5.581024K51224IDAC, PWM1212V



General Description

GPC22F340A is embedded with an 8- bit processor, 1024KB E-Flash, 512B SRAM, three 12-bit timers, 24 general I/Os, one pure input port, one 12-bit current DAC.  For audio processing, two channels of speech or two tone generators can be used by controlled register. GPC22F340A operates over a wide voltage range of 2.0V - 5.5V and includes Low Voltage Reset function.  In addition, GPC22F340A provides sleep mode for power savings.  It wakes up from sleep mode by interrupt sources or by IO’s state change.  There is a Serial Peripheral Interface (SPI) controller built-in GPC22F340A to facilitate communicating with other devices and components.
