70 / 110 page  TMS570LS0432, TMS570LS0332 SPNS186B – OCTOBER 2012 – REVISED JUNE 2015 www.ti.com 7 Peripheral Information and Electrical Specifications 7.1 Peripheral Legend Table 7-1. Peripheral Legend ABBREVIATION FULL NAME MibADC Multibuffered Analog-to-Digital Converter CCM-R4 CPU Compare Module – Cortex-R4 CRC Cyclic Redundancy Check DCAN Controller Area Network DCC Dual Clock Comparator ESM Error Signaling Module GIO General-Purpose Input/Output HTU High-End Timer Transfer Unit LIN Local Interconnect Network MibSPI Multibuffered Serial Peripheral Interface N2HET Platform High-End Timer RTI Real-Time Interrupt Module SCI Serial Communications Interface SPI Serial Peripheral Interface VIM Vectored Interrupt Manager eQEP Enhanced Quadrature Encoder Pulse 7.2 Multibuffered 12-Bit 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 7-2. MibADC Overview DESCRIPTION VALUE Resolution 12 bits Monotonic Assured Output conversion code 00h to FFFh [00 for VAI ≤ ADREFLO; FFF for VAI ≥ ADREFHI] 7.2.1 Features • 12-bit resolution • ADREFHI and ADREFLO pins (high and low reference voltages) • Total Sample/Hold/Convert time: 600 ns Typical Minimum at 30 MHz 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 by interrupt • Programmable interrupt threshold counter is available for each group • Programmable magnitude threshold interrupt for each group for any one channel • Option to read either 8-, or 10-, or 12-bit values from memory regions • Single or continuous conversion modes • Embedded self-test • Embedded calibration logic • Enhanced power-down mode – Optional feature to automatically power down ADC core when no conversion is in progress 70 Peripheral Information and Electrical Specifications Copyright © 2012–2015, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TMS570LS0432 TMS570LS0332 |
