TR16F900B General Description:
The TxP16ETM is a high performance 16-bit MCU, running up to 32MHz and provided with 64K FLASH and total 4K SRAM for high performance process of voice recognition algorithm, power control and motor control. It is the new generation computational kernel for Flash DSP series. It has initially aimed at the areas of controller and multimedia digital signal processing (DSP) application to demonstrate its profession. TxP16E furnish with fast MAC architecture, which allows multiplication+accumulation instructions to be issued with access memory simultaneously during one cycles. The TR16F900 is equipped with TxP16E and integrating input/output ports,Audio PWM, Timer and Low Voltage Reset...etc on a chip.
Furthermore, TR16F900 extend its external device connection capability such as Serial ROM/Flash. The internal memory capacity includes 64Kx16 program/data FLASH plus 4Kx16 working SRAM.

TR16F900B Block Diagram:
TR16F900B MAC (16-bit X 16-bit Multiplier and Accumulator):
A 16 bit x 16 bit MAC is provided for digital signal processing. The core of MAC operation is multiply MX&MY
with 2’S complement operand and accumulation previous 40-bit MF then rounding store result in the 40-bit MR
register. The basic MAC architecture is shown as Figure 5.5.

TR16F900B High speed 8-Channels / 10-bits ADC Structure Diagram:
Note: If user need more precise ADC for application, user can set “ADC vref input” to enable VREFI at
option. If ADC Verf input is enabled, PortC2 must be connected 20~100ohm resistor to VCC and 47uF
capacitor to AVSS. Otherwise, IC does not work properly.
Note: Enable ADC verf input at option, PortC2 is as ADC voltage-reference input(VREFI), not as I/O pin.
** The decouple capacitor (10uF) must be as near as possible to VCC and VSS.
