  Vocoder Implementation Using TMS470 High-End Timer
  PDF, 326 Kb, File published: Jan 8, 2007
  The TMS470 family of ARM7 microcontrollers contains a RISC coprocessor referred to as the High-End Timer (HET). The HET can implement complex I/O operations independent from the CPU, one of which is the capability to generate PWM signals. This application report describes using this PWM capability, along with an open source voice algorithm called Speex, to encode 8-bit voice messages without the n

  UART Implementation Using the High-End Timer
  PDF, 120 Kb, File published: Jun 9, 2006
  This application report describes how the TMS470 high-end timer (HET) peripheral can be used to implement multiple additional full-duplex high-speed universal asynchronous receiver transmitter (UART) interfaces with interrupt capability and zero ARM7 CPU overhead. The solution is provided for both TMS470R1A256 and TMS470R1B1M devices, but the information applies to other TMS470 family members as w

  TMS470 Expansion Bus Module Example
  PDF, 126 Kb, File published: Dec 20, 2006
  This document supplies information for using the Expansion Bus Module (EBM) on the TMS470R1B1M to interface to external memory and peripherals. The module supports the multiplexing of the input/output (I/O) functions and the expansion bus interface. When the I/O functions are not used, the EBM can be used to interface 8- or 16-bit memories.

  3.3 V I/O Considerations for Hercules Safety MCUs (Rev. A)
  PDF, 103 Kb, Revision: A, File published: Sep 6, 2011
  As new generations of microcontrollers lower their supply voltages from 5 V to 3.3 V and beyond, issues with interfacing and noise are increasing. This application report presents cost-effective interfacing techniques for inputs and outputs of 3.3 V microprocessors in an automotive environment. In addition, concerns about 3.3 V analog-to-digital converters (ADC) are discussed.
