116 / 159 page  TMS570LS3137 SPNS162. – SEPTEMBER 2011 www.ti.com 5 Peripheral Information and Electrical Specifications 5.1 Peripheral Legend Table 5-1. Peripheral Legend Abbreviation Full Name MibADC Analog To Digital Converter CCM-R4F CPU Compare Module - CortexR4F CRC Cyclic Redundancy Check DCAN Controller Area Network DCC Dual Clock Comparator DMA Direct Memory Access DMM Data Modification Module EMIF External Memory Interface ESM Error Signaling Module ETM-R4F Embedded Trace Macrocell - CortexR4F FTU FlexRay Transfer Unit GIO General-Purpose Input/Output HTU High End Timer Transfer Unit I2C Inter-Integrated Circuit LIN Local Interconnect Network MIBSPI Multibuffer Serial Peripheral Interface N2HET Platform High-End Timer POM Parameter Overlay Module RTI Real-Time Interrupt Module RTP RAM Trace Port SCI Serial Communications Interface SPI Serial Peripheral Interface VIM Vectored Interrupt Manager 5.2 Multi-Buffered 12bit Analog-to-Digital Converter The multibuffered A-to-D converter (MibADC) has a separate power bus for its analog circuitry that enhances the A-to-D performance by preventing digital switching noise on the logic circuitry which could be present on VSS and VCC from coupling into the A-to-D analog stage. All A-to-D specifications are given with respect to ADREFLO unless otherwise noted. Table 5-2. MibADC Overview Description Value Resolution 12 bits Monotonic Assured Output conversion code 00h to FFFh [00 for VAI ≤ ADREFLO; FFF for VAI ≥ ADREFHI] 5.2.1 Features • 10-/12-bit resolution • ADREFHI and ADREFLO pins (high and low reference voltages) • Total Sample/Hold/Convert time: 600ns Typical Minimum at 30MHz ADCLK • One memory region per conversion group is available (event, group 1, group 2) • Allocation of channels to conversion groups is completely programmable • Memory regions are serviced either by interrupt or by DMA 116 Peripheral Information and Electrical Specifications Copyright © 2011, Texas Instruments Incorporated Submit Documentation Feedback focus.ti.com: TMS570LS3137 |
