Product details
Overview
AM4376BZDN100 from Texas Instruments is a high-performance Sitara™ ARM® Cortex®-A9 processor operating at 800 MHz, integrating dual 12-bit SAR ADCs (867 kSPS), six eHRPWM modules, three eQEP modules, and a programmable PRU-ICSS subsystem supporting EtherCAT®, PROFINET®, and EnDat 2.2 for industrial real-time control. It features 32KB L1 instruction/data cache, 256KB L2 cache, LPDDR2/DDR3/DDR3L memory support, and a PowerVR SGX530 graphics engine enabling WXGA display output.
For engineers reviewing the AM4376BZDN100 datasheet, AM4376BZDN100 pinout, AM4376BZDN100 application, or AM4376BZDN100 equivalent, key selection criteria include its 491-ball NFBGA (17 mm × 17 mm, 0.65 mm pitch) package, industrial temperature range (–40°C to +105°C), dual CAN 2.0B ports, six UARTs with IrDA/CIR support, and integrated touch-screen controller (TSC) capability via ADC0.
Technical Context
The AM4376BZDN100 implements a dual-core-capable ARM Cortex-A9 MPCore subsystem with NEON SIMD and VFPv3 coprocessors, coupled with a dedicated PRU-ICSS containing two 200-MHz programmable real-time units-each with 12KB instruction RAM and 8KB data RAM-for deterministic protocol offload. Its memory subsystem includes 32-bit DDR3/DDR3L/LPDDR2 interfaces (400-MHz clock, DDR-800 data rate) and a flexible GPMC supporting NAND/NOR/SRAM with up to 16-bit ECC.
Power management uses five ADPLLs to generate independent clocks for MPU, DDR, USB, peripherals, and graphics, while dynamic voltage-frequency scaling (DVFS) enables operation across multiple performance points. The device integrates IEEE 1588v2 PTP support in both Ethernet MACs and provides hardware crypto acceleration (AES, SHA, RNG, DES, 3DES) alongside secure boot capability on HS variants-though AM4376BZDN100 is not an HS part.

The AM4376BZDN100 features an ARM Cortex-A9 processor core rated for operation at 800 MHz, delivering 2000 MIPS of computational performance. This frequency is validated across the full industrial temperature range (–40°C to +105°C) and supported by TI's recommended operating conditions, including specific voltage and cooling requirements outlined in the SPRS851E datasheet.
Does the AM4376BZDN100 support secure boot functionality?
No, the AM4376BZDN100 does not support secure boot. Secure boot is only available on AM437x High-Security (HS) variants, which are explicitly designated in the part number (e.g., AM4376BZDNA). The AM4376BZDN100 is a standard-security device and lacks the fuse farm programming, secure control module (SCM), and cryptographic key storage required for authenticated boot.
How many Ethernet ports does the AM4376BZDN100 integrate, and what speeds are supported?
The AM4376BZDN100 integrates two Ethernet media access controllers (EMACs) with an on-chip 2-port switch, supporting 10/100/1000 Mbps operation per port. Each EMAC supports MII, RMII, and RGMII physical layer interfaces and includes IEEE 1588v2 Precision Time Protocol (PTP) hardware timestamping for synchronized industrial networking.
Can the AM4376BZDN100 directly interface with a resistive touch screen?
Yes, the AM4376BZDN100 can directly interface with a 4-, 5-, or 8-wire resistive touch screen using its ADC0 subsystem. The device's integrated touch screen controller (TSC) mode configures ADC0's analog input multiplexer and sequencer to perform coordinate acquisition without external components, reducing system BOM and simplifying layout for HMI applications.
What type of graphics acceleration does the AM4376BZDN100 provide?
The AM4376BZDN100 integrates a PowerVR SGX530 3D graphics engine capable of up to 20 million triangles per second.
