The TxP16S2TM is a high-performance 16-bit MCU operating at up to 32MHz with 512K FLASH and 4K SRAM for high-performance processing of audio algorithms. It is a new generation of computing cores in the Flash Speech family. It initially targeted the field of voice applications to demonstrate its expertise. The TxP16S2 provides a fast unit that allows computation instructions to be issued simultaneously to the access memory in one cycle. The TRSF1608A(C) is equipped with TxP16S2 and integrated input/output ports, audio PWM/DAC, timer and low voltage reset. Let's wait.
    In addition, the TRSF1608A(C) extends its external device connectivity capabilities, such as serial ROM/Flash. Internal memory capacity includes 512Kx16 program/data FLASH and 4Kx16 working SRAM.

* Note: TRSF1608C only supports SOP16-3 and SSOP24-2 packages.
* Note: TRSF1608A(C) does not support ultra-deep sleep.
* Note: Port C2 must not be connected to VCC or pull-up resistors.
* Note: The TRSF1608A(C) does not support buzzer and speaker wake-up, so MISC1 bit 10, MISC2 bit 12, and MISC2 bit 14 should be set to 0.

16-bit x 16-bit MAC is available for digital signal processing. The core of MAC operations is multiplication MX&MY
Use 2's complement operand and the sum of the previous 40-bit MF, then round the stored results into the 40-bit MR To register the basic MAC architecture as shown in Figure 5.5.

Application circuit: MONO16-bit PWM output
Attention:
1. The VCC decoupling cap 10uF should be close to the IC within 0.5cm.
2.VCC decoupling cap 0.1uF should be close to IC 0.5cm.
3. In the PCB layout, the width of the VCC and VSS power cables should be greater than 30 mil.
