4 / 67 page  TMS470MF04207 TMS470MF03107 SPNS159C – JANUARY 2012 www.ti.com rates of up to 1 megabit per second (Mbps). The DCAN is ideal for applications operating in noisy and harsh environments (e.g., automotive and industrial fields) that require reliable serial communication or multiplexed wiring. The MibSPI provides a convenient method of serial interaction for high-speed communications between similar shift-register type devices. The MibSPI provides the standard SOMI, SIMO, and SPI clock interface as well as up to eight chip select lines. The HET is an advanced intelligent timer that provides sophisticated timing functions for real-time applications. The timer is software-controlled, using a reduced instruction set, with a specialized timer micromachine and an attached I/O port. The HET can be used for compare, capture, or general-purpose I/O. It is especially well suited for applications requiring multiple sensor information and drive actuators with complex and accurate time pulses. The TMS470M HET peripheral contains the XOR-share feature. This feature allows two adjacent HET high- resolution channels to be XORed together, making it possible to output smaller pulses than a standard HET. The TMS470M devices have one 10-bit-resolution, sample-and-hold MibADC. Each of the MibADC channels can be grouped by software for sequential conversion sequences. There are three separate groupings, all three of which can be triggered by an external event. Each sequence can be converted once when triggered or configured for continuous conversion mode. The frequency-modulated zero-pin phase-locked loop (FMzPLL) clock module contains a phase-locked loop, a clock-monitor circuit, a clock-enable circuit, and a prescaler. The function of the FMzPLL is to multiply the external frequency reference to a higher frequency for internal use. The FMzPLL provides the input to the global clock module (GCM). The GCM module subsequently provides system clock (HCLK), real-time interrupt clock (RTICLK), CPU clock (GCLK), HET clock (VCLK2), DCAN clock (AVCLK1), and peripheral interface clock (VCLK) to all other TMS470M device modules. The TMS470MF04207/TMS470MF03107 devices also have two external clock prescaler (ECP) modules that when enabled, output a continuous external clock (ECLK). The ECLK1 frequency is a user-programmable ratio of the peripheral interface clock (VCLK) frequency. The second ECLK output can be selected in place of HET15 output. It shares the same source clock as ECLK1 but can be independently programmed for a separate output frequency from ECLK1. An error signaling module (ESM) provides a common location within the device for error reporting allowing efficient error checking and identification. 4 Features Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): TMS470MF04207 TMS470MF03107 |
