Product details
Overview
AM4377BZDNA100 from Texas Instruments is a high-performance Sitara™ ARM® Cortex®-A9 microprocessor operating at 1 GHz, integrating dual 12-bit SAR ADCs (867 kSPS), six eHRPWM modules, three eQEP modules, PRU-ICSS for EtherCAT/PROFINET, and PowerVR SGX530 3D graphics. It supports LPDDR2/DDR3/DDR3L memory, dual USB 2.0 with PHY, dual Gigabit Ethernet with IEEE 1588v2, and industrial I/O including CAN, McSPI, UART, and I²C - deployed in programmable logic controllers and motor control HMI systems.
For engineers reviewing the AM4377BZDNA100 datasheet, AM4377BZDNA100 pinout, AM4377BZDNA100 application, or AM4377BZDNA100 equivalent, this page delivers verified technical context, validated package mapping to 491-pin ZDN NFBGA, confirmed PRU-ICSS real-time protocol support, exact L2 cache size (256 KB), and documented ADC0 touch-screen controller capability - all essential for industrial SoC selection and PCB layout planning.
Technical Context
The AM4377BZDNA100 implements a dual-core-capable ARM Cortex-A9 subsystem running at 1000 MHz with 32KB L1 instruction/data caches and 256KB configurable L2 cache or L3 RAM. Its PRU-ICSS contains two independent 200-MHz RISC cores with dedicated 12KB/4KB instruction/data RAM per subsystem, enabling parallel execution of EtherCAT and EnDat 2.2 on separate PRU-ICSS instances without CPU intervention.
It integrates a full-featured display subsystem supporting up to 2048×2048 resolution with RGB24/YUV422 formats, hardware-accelerated overlay, gamma correction, and partial frame buffer refresh via RFBI - paired with ADC0 configured as 4-/5-/8-wire resistive touch screen controller for integrated HMI front-ends.

FAQ
What is the maximum operating frequency of the AM4377BZDNA100 processor core?
The AM4377BZDNA100 features an ARM Cortex-A9 processor core rated for operation at up to 1000 MHz. This frequency is validated under specified thermal and voltage conditions per TI's SPRS851E datasheet, and enables high-throughput execution of Linux-based industrial applications, real-time control stacks, and graphics-intensive HMIs without throttling in standard 0°C to 90°C ambient environments.
Does the AM4377BZDNA100 support secure boot functionality?
No, the AM4377BZDNA100 does not support secure boot. Secure boot is available only on AM437x High-Security (HS) variants such as AM4377BZDNA100HS. The standard AM4377BZDNA100 lacks the Secure Control Module (SCM), encrypted boot ROM, and cryptographic key storage required for authenticated firmware loading.
How many PRU-ICSS subsystems does the AM4377BZDNA100 include, and what protocols do they support?
The AM4377BZDNA100 includes two fully independent PRU-ICSS subsystems - PRU-ICSS0 and PRU-ICSS1 - each with dedicated 200-MHz RISC cores, instruction/data RAM, and peripherals. They support EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, EnDat 2.2, and Sercos simultaneously, with one subsystem typically assigned to fieldbus I/O scanning and the other to position feedback or custom protocol implementation.
What display resolutions and interfaces are supported by the AM4377BZDNA100's display subsystem?
The AM4377BZDNA100 display subsystem supports resolutions up to 2048×2048 pixels, with native WXGA (1366×768) at 60 Hz. It provides RGB8/12/16/18/24, YUV422, and palletized pixel formats over parallel 14-bit DSS data bus (dss_data0–dss_data13), plus Remote Frame Buffer Interface (RFBI) for embedded LCD panels with partial refresh capability.
Can the AM4377BZDNA100's ADC0 be used as a touch screen controller, and what configurations are supported?
Yes, ADC0 in the AM4377BZDNA100 can be configured as a 4-wire, 5-wire, or 8-wire resistive touch screen controller (TSC). This capability is implemented in hardware and requires no external touch controller IC. The TSC function shares the eight analog input channels and supports pressure measurement, coordinate acquisition, and debounce filtering - directly interfacing with standard 4-wire resistive overlays.
