.1. General Introduction
BT-V2.0(BK3513) is a Bluetooth 2.1 class 2 modules which is a high performance, cost
effective, low power and compact solution. The Bluetooth class 2 module provides a complete
2.4GHz Bluetooth system based on BK3513 chip which is a single chip radio and baseband
IC for Bluetooth 2.4GHz systems. This module is fully compliant to Bluetooth v2.1 for audio
communications.
The AC410x family is a low-power, high-performance microprocessor with 96KB SRAM,
which incorporates a 32-bit RISC CPU, a high-speed digital signal processor(DSP) and rich
peripheral circuits. Key features of the AC410x family include:
---- 36 Programmable GPIO.
---- Support Watch Dog (WDT) and RTC.
---- 24 Interrupt Sources and 4 interrupt priority level.
---- Support idle/standby/sleep low power mode and IO wakeup.
---- Two 8bit and two 16bit Timer/Counters, supports PWM mode and capture function.
---- 16bit stereo DAC with Headphone Amplifier.
---- 16bit ADC with Microphone Amplifier.
---- Two full-duplex UART, and UART0 supports DMA.
---- Two SPI controller supports master and slave, and DMA.
---- Two SD master controller supports DMA.
---- One full speed USB2.0 controller which supports master and slave.
---- One IIC and one IIS controller.
The AC410x family is a powerful microprocessor with rich peripheral resources which
provides a highly flexible and cost effective solution to many embedded control applications.
