GPC3340D数据手册Generalplus中文资料规格书

描述 Description

The GPC3340D is embedded with an 8-bit processor, 32K~2M bytes ROM or OTP ROM (by body), 96~256 bytes working SRAM, three sets of 12-bit timer/counters, 12~24 general I/Os, a 3-channel mixer, a pair of 12-bit PWM outputs and a Real Time Clock (by body).  In audio processing, melody and speech can be mixed into one output.  It operates over a wide voltage range and has a 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 changes.  GPC3340D is one of the most suitable speech engines in the industry for vocal applications.

特性 Features

• Wide Operating Voltage: 2.0V/2.1V * - 5.5V (by body)
* The lowest operating voltage depends on LVR (Low Voltage Reset) level. Typical LVR voltage is 2.0V/2.1V (by body), 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** The system clock would start to slow down at lowest working voltage (6MHz at 2.2V, 8MHz at 2.4V); please refer to the Frequency vs. VDD curve on page 16 and page 17
• ROM size: 32K~2M bytes (by body)
• RAM size: 96 ~256 bytes (by body)
• Built-in internal or external RC oscillator (by body)
• Built-in internal RC oscillator 8MHz or 6MHz(code option)
• Approx. 10~680 seconds speech @6KHz sampling rate with 4-bit ADPCM (by body)
• Standby mode (Clock Stop mode) for power savings.
  Max. 2.0uA ~ 5.0uA @ 4.5V (by body)
• Bit programmable 12~24 general I/Os(by body)
• 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 timer/counters
• 7 or 8 IRQs & 1 NMI interrupt (by body)
• 2 or 3 wake-up sources (by body)
• Feedback function (by body)
• Low Voltage Reset (LVR) function
• Watchdog function
• IR function
• RTC function (by body)
• Four sets of hardware PWMIO support LED outputs with brightness control of 256-level
• A 3-channel mixer with melody or ADPCM/PCM input
• A pair of PWM outputs with volume control
