描述 Description

The easy-to-use SOUNDPLUS II (GPESII) is an enhanced version of easy-to-use SOUNDPLUS (GPES). Many features have been added in GPES II to increase its capability and performance. One of the most significant features in GPES II is that no complex program structure is necessary. With only nine instructions and six registers, GPES II is capable of driving sophisticated tasks and playing realistic sound with simple program structure. Programmer can easily implement application rapidly and increase productivity efficiently.The GPES220B2, one of the GPES II families, stores up to 20 seconds of sound data (@ 6.0KHz sample rate). It also contains four trigger pins, eight output pins, PWM audio output, and five LED flash alternations. To assure the system reliability, a watchdog and a Low Voltage Reset (LVR) are also built in for monitoring possible critical conditions. With the high cost/performance ratio, GPES220B2 is one of the most suitable engines in the industry for vocal products.
