描述 Description

GPCR20A is a highly integrated circuit that contains all of the necessary functions for providing high quality voice recording and playback. In order to provide the high quality voice, 4 times over sampling and 19 level digital filter technology are used to reduce the noise level. Easy-to-use, low power consumption and compact size are the tremendous features of GPCR20A. Total of 512K bits SRAM are capable of storing approximately 20 seconds of audio or speech voice (@6KHz sampling rate). PWM speaker driver offers the simplest output solution for users. Furthemore, the wide operating power supply (2.4V~5.5V) provides various battery options to select. The development team of GPCR20A designs especially for compact message recorder, recordable toys and other similar products. It is welling to provide the best cost/performance ratio for users.
