Description
The TMS570LS0914 device is part of the Hercules TMS570 series of high-performance automotive-grade
ARM® Cortex®-R-based MCUs. Comprehensive documentation, tools, and software are available to
assist in the development of ISO 26262 and IEC 61508 functional safety applications. Start evaluating
today with the Hercules TMS570 LaunchPad Development Kit. The TMS570LS0914 device has on-chip
diagnostic features including: dual CPUs in lockstep; CPU and memory Built-In Self-Test (BIST) logic;
ECC on both the flash and the SRAM; parity on peripheral memories; and loopback capability on most
peripheral I/Os.
The TMS570LS0914 device integrates the ARM Cortex-R4F floating-point CPU which offers an efficient
1.66 DMIPS/MHz, and has configurations which can run up to 160 MHz providing up to 265 DMIPS. The
TMS570 device supports the word invariant big-endian [BE32] format.
The TMS570LS0914 device has 1MB of integrated flash and 128KB of RAM configurations with single-bit
error correction and double-bit error detection. The flash memory on this device is nonvolatile, electrically
erasable and programmable, and is implemented with a 64-bit-wide data bus interface. The flash operates
on a 3.3-V supply input (same level as the I/O supply) for all read, program, and erase operations. The
SRAM supports single-cycle read and write accesses in byte, halfword, word, and doubleword modes
throughout the supported frequency range.
The TMS570LS0914 device features peripherals for real-time control-based applications, including two
Next-Generation High-End Timer (N2HET) timing coprocessors with up to 44 total I/O terminals, seven
Enhanced PWM (ePWM) modules with up to 14 outputs, six Enhanced Capture (eCAP) modules, two
Enhanced Quadrature Encoder Pulse (eQEP) modules, and two 12-bit Analog-to-Digital Converters
(ADCs) supporting up to 24 inputs.
The N2HET 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 N2HET can be used for pulse-width-modulated outputs,
capture or compare inputs, or general-purpose I/O (GIO). The N2HET is especially well suited for
applications requiring multiple sensor information and drive actuators with complex and accurate time
pulses. A High-End Timer Transfer Unit (HTU) can transfer N2HET data to or from main memory. A
Memory Protection Unit (MPU) is built into the HTU.
The ePWM module can generate complex pulse width waveforms with minimal CPU overhead or
intervention. The ePWM is easy to use and supports complementary PWMs and deadband generation.
With integrated trip zone protection and synchronization with the on-chip MibADC, the ePWM is ideal for
digital motor control applications.
The eCAP module is essential in systems where the accurately timed capture of external events is
important. The eCAP can also be used to monitor the ePWM outputs or to generate simple PWM when
not needed for capture applications.
The eQEP module is used for direct interface with a linear or rotary incremental encoder to get position,
direction, and speed information from a rotating machine as used in high-performance motion and
position-control systems.
The device has two 12-bit-resolution MibADCs with 24 total inputs and 64 words of parity-protected buffer
RAM each. The MibADC channels can be converted individually or can be grouped by software for
sequential conversion sequences. Sixteen inputs are shared between the two MibADCs. There are three
separate groups. Each group can be converted once when triggered or configured for continuous
conversion mode. The MibADC has a 10-bit mode for use when compatibility with older devices or faster
conversion time is desired.
