General Description
GPC3341A is the OTP (One-Time-Programming) version of the GPC3 family. GPC3341A is embedded with an 8-bit processor, 1M bytes OTP ROM, 128-byte working SRAM, three sets of 12-bit timer/counters, 24 general I/Os, a 3-channel mixer, a pair of 12-bit PWM outputs and a Real Time Clock(RTC). The microprocessor can implement software based on audio processing, functional control and others. For audio processing, melody and speech can be mixed into one output. It operates a wide voltage range from 2.0V through 5.5V, and it also features a Low Voltage Reset function to assure the system is capable of operating under a low voltage condition. In addition, GPC3341A provides sleep mode for power saving. It can be awakened from sleep mode by interrupting sources or changing IO's states. With the high cost/performance, GPC3341A is one of the most suitable speech engines in the industry for vocal applications.
Features
- Wide Operating Voltage: 2.0V * - 5.5V
* The lowest operating voltage depends on LVR (Low Voltage Reset) level. Typical LVR voltage is 2.0V but with +/- 0.1V deviation possibility. - Working voltage with 6MHz system clock: 2.2V ** - 5.5V
- Working voltage with 8MHz system clock: 2.4V ** - 5.5V
** When using internal oscillator, the system clock would start to slow down at lowest working voltage(6MHz at 2.2V, 8MHz at 2.4V) - 1M bytes ROM
- 128-byte working SRAM
- Built-in internal or external RC oscillator嚗ode option嚗?/li>
- Built-in internal RC oscillator 8MHz or 6MHz嚗ode option嚗?/li>
- Approx. 340 seconds speech @6KHz sampling rate with 4-bit ADPCM
- Standby mode (Clock Stop mode) for power savings. Max. 5.0uA @ 4.5V
- Bit programmable 24 general I/Os
- 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 VDD)
- Three 12-bit timers/counters
- 8 IRQs & 1 NMI interrupt
- Three wake-up sources
- Low Voltage Reset (LVR) function
- Watchdog function
- IR function
- RTC function
- Four sets of hardware PWMIO support LED outputs with 256-level brightness control
- A 3-channel mixer with melody or ADPCM/PCM input
- A pair of PWM outputs with volume control
