描述 Description

GPC3P340A1 is embedded with an 8-bit processor, 288K~1M bytes OTP ROM (by body), 128 bytes SRAM, three 12-bit timer/counters, 16 or 24 general I/Os, a 3-channel mixer, a pair of 12-bit PWM outputs and a real time clock.? In audio processing, melody and speech can be mixed into one output. ?It operates over a wide voltage range and has an low voltage reset function and a sleep mode to save more power. ?It can be awakened from sleep mode by interrupt sources or IO’s state change. ?GPC3P340A1 is one of the most suitable speech engines in the industry for vocal applications.

特性 Features

? Wide Operating Voltage: 2.0V - 5.5V
* The lowest operating voltage depends on LVR (Low Voltage Reset) level. Typical LVR voltage is 1.9V, but with +/- 0.1V deviation possibility.
? ROM size: 288K~1M bytes (by body)
? RAM size: 128 bytes
? Built-in internal RC oscillator 8MHz or 6MHz(body option)
? 92~340 seconds of speech duration at 6KHz sampling rate in 4-bit ADPCM format (by body option)
? Standby mode (Clock Stop mode) for power savings.
Max. 5.0uA ~ 10.0uA @ 4.5V
? 16 or 24 general I/Os(by body) with bit-programmable function and one input pin with pull low resistor(by body option)
? Four I/Os with high sink current for LED application
? All general IOs provide 1M pull-low function to prevent current leakage while pressing the key (IOs to VDDIO)
? Three 12-bit timer/counters
? Eight IRQs & 1 NMI interrupt
? Two or three wakeup sources
? Low Voltage Reset (LVR) function
? Watchdog function
? IR function
? RTC function (by body option)
? Four sets of hardware PWMIO supporting LED outputs with brightness control of 256-level
? A three-channel mixer with melody or ADPCM/PCM input
? A pair of PWM outputs with volume control
? Low Voltage Detection(LVD), one-level 2.2V voltage detector
? Battery Voltage Detection(BVD), 3-bit status display on VDD5V level from 2.2V ~ 3.4V
