AM13E232x microcontrollers (MCUs) are part of the AM13E2x highly integrated, low-cost 32-bit MCU family based on the enhanced Arm Cortex-M33 32-bit core platform operating at up to 250MHz frequency. These cost-optimized MCUs offer high-performance analog, control, and digital peripheral integration, support ambient temperature ranges from -40°C to 125°C, and operate with a 3.3V supply voltage.

The AM13E232x MCUs provide up to 512KB of embedded flash program memory (2 banks of 256KB) with built-in error correction code (ECC) and up to 192 KB SRAM with hardware parity.

The core of the MCUs incorporate Custom Datapath Extension (CDE) support, a Memory Protection Unit (MPU), Micro Trace Buffer (MTB), a 32-bit Trigonometric Math Unit (TMU), and a Neural-network Processing Unit (NPU).

AM13E232x MCUs are enabled with robust, high-performance analog peripherals. Three 12-bit ADCs with a maximum sampling rate of 7.81MSPS at 250MHz, eight high speed comparators with built-in 12-bit reference DACs, and three programmable gain amplifiers provide optimal real-time signal chain performance.

These MCUs also offer intelligent digital peripherals such as two advanced control timers (one 16-bit, one 32-bit), one Windowed Watchdog Timer (WWDT), one Watchdog Timer (WDT), and a 12-channel Direct Memory Access (DMA) controller.

Complex real-time control applications are enabled with the MCUs’ three MCPWM modules with 6 channels per module, 12 channels of ePWM with high resolution, three Enhanced Capture (ECAP) modules, and two Enganced Quadrature Encoder Pulse (EQEP) modules.

Data integrity and encryption features (AES, secure boot) provide security across the AM13E232x domains. A Cyclic Redundancy Checker (CRC) module provides internal diagnostics to the AM13E232x MCU.

Enhanced communication interfaces are supported through the two MCAN interface and two advanced UNICOMM peripherals. The four UNICOMM block offers configurations for up to four UART, four I2C, or two SPI interfaces.

An EtherCAT SubDevice Controller is available on this device. The Fast Serial Interface (FSI) enables up to 200Mbps of robust communications across an isolation boundary.

The TI AM13E2x family of MCUs consists of devices with varying degrees of analog and digital integration that allow customers to find the MCU that meets project needs, with 3 device package options to choose from. The AM13E2x MCU platform combines the Arm Cortex-M33 platform with a holistic low-power system architecture, allowing system designers to increase performance while reducing energy consumption.
