Product details
Overview
HPA-MCU Interface Board from Texas Instruments is a modular evaluation interface platform designed to connect microcontrollers and DSPs-including TMS320F2407, TMS320F2808, TMS320F2812, and TMS470R1A1024-to TI data converter EVMs via parallel, serial (SPI/McBSP/SCI/I²C), and CAN interfaces. It supports analog signal conditioning, dual serial EVM sites, and one parallel EVM site with 16-bit data bus and 4-bit address decoding.
For engineers reviewing the HPA-MCU Interface Board datasheet, HPA-MCU Interface Board pinout, HPA-MCU Interface Board application, or HPA-MCU Interface Board equivalent, key selection considerations include compatibility with TI C2000 DSPs and MSP430/TMS470 MCUs, support for SCI/RS-232 loopback testing via SW2, CAN transceiver integration (SN65HVD235), and flexible power routing for analog/digital domains across multiple EVM sites.
Technical Context
The board implements three distinct interface domains: (1) Parallel site with J13 (20-pin control header) and J14 (32-pin 16-bit data bus), supporting chip select, read/write strobes, and A2–A5/A12–A15 address muxing via SN74CBTLV3257; (2) Dual serial sites (J11/J12) with configurable SPI/McBSP routing using SN74CBTLV3257 multiplexers and SN74CBTD3861 bus switches.
It integrates TI interface ICs including MAX3232 (dual RS-232 transceiver), SN65HVD235 (3.3V CAN transceiver with internal loopback), and SN74LVTH16245 (16-bit level-shifting bus transceivers), enabling simultaneous SCI, CAN, and parallel communication paths to connected EVMs while maintaining independent analog/digital power domains.

FAQ
What microcontrollers and DSPs are compatible with the HPA-MCU Interface Board?
The HPA-MCU Interface Board is explicitly validated for use with Texas Instruments TMS320F2407, TMS320F2808, and TMS320F2812 eZdsp™ platforms from Spectrum Digital, as well as the TMS470R1A1024 microcontroller. Compatibility is achieved through dedicated pin-header interfaces (J15 for parallel bus, J16 for McBSP, J17 for GPIO/SCI/SPI/CAN/I²C) and documented signal mappings in SLAU106.
Does the HPA-MCU Interface Board support CAN communication, and how is it implemented?
Yes, the HPA-MCU Interface Board supports CAN 2.0B communication via U10 (SN65HVD235 3.3V CAN transceiver) connected to J20. It provides internal loopback capability when jumper W2 is closed, and supports external CAN node connection through the DB9 connector. CAN signals (CANTXa/CANRXa) are also routed to J11/J12 serial headers for direct processor-level access.
How does the HPA-MCU Interface Board handle power distribution for connected EVMs?
The HPA-MCU Interface Board provides segregated analog and digital power domains: ±15V/±5V analog via screw terminals J1/J4; +1.8V/+3.3V/+5V digital via J7–J10; and optional MCU board power (+3.3V via R7 or +5V via R8). Power connectors JP1–JP4 (signal conditioning) and JP5–JP6 (serial sites) replicate these rails with identical pinouts for modularity and stacking flexibility.
Can the HPA-MCU Interface Board be used for RS-232 loopback testing, and what hardware enables this?
Yes, the HPA-MCU Interface Board supports RS-232 loopback testing via DPDT switch SW2, which swaps TX/RX lines on SCI Port 1 (J18). In "null modem" position, SCITXDa connects to J18 pin 3 and SCIRXDa to pin 2-enabling self-test without external cabling. The dual MAX3232 (U7) provides level translation for both SCI ports (J18/J19), supporting standard 9-pin serial cables.
What types of data converter EVMs can be connected to the HPA-MCU Interface Board?
The HPA-MCU Interface Board supports modular Texas Instruments data converter EVMs-including ADCs, DACs, and CODECs-that conform to the SLAA185 modular EVM design guidelines. It accommodates analog signal conditioning boards (via J2/J3), serial EVMs (J11/J12 with SPI/McBSP), and parallel EVMs (J13/J14 with 16-bit data bus), enabling full signal chain evaluation from sensor to digital domain using the HPA-MCU Interface Board.
