Texas Instruments AMIC120BZDNA30

Overview

AMIC120BZDNA30 from Texas Instruments is a Sitara™ ARM® Cortex®-A9 32-bit RISC processor operating at up to 300 MHz, featuring 32KB L1 instruction and data cache, 256KB L2 cache (configurable as L3 RAM), dual USB 2.0 high-speed dual-role ports with integrated PHY, and industrial Ethernet support via a 1-port 10/100/1000 Mbps EMAC switch with IEEE 1588v2 PTP - deployed in programmable logic controller (PLC) backplane I/O modules requiring deterministic real-time protocol offload.

For engineers reviewing the AMIC120BZDNA30 datasheet, AMIC120BZDNA30 pinout, AMIC120BZDNA30 application, or AMIC120BZDNA30 equivalent, key selection criteria include PRU-ICSS subsystem availability for EtherCAT/PROFINET offload, 491-ball NFBGA package routing compatibility, LPDDR2/DDR3/DDR3L memory interface timing compliance, and dual 12-bit SAR ADC integration for analog sensor interfacing in industrial edge nodes.

Technical Context

The AMIC120BZDNA30 integrates a dual-core-capable ARM Cortex-A9 MPU subsystem with NEON SIMD and VFPv3 coprocessors, coupled with two independent PRU-ICSS subsystems - each containing two 200-MHz 32-bit RISC PRU cores, dedicated instruction/data RAM with parity, and hardware peripherals including UART, eCAP, MII Ethernet, and MDIO - enabling concurrent execution of Linux-based HLOS and hard real-time industrial protocols without CPU intervention.

Its memory architecture supports 32-bit LPDDR2 (266-MHz clock), DDR3/DDR3L (400-MHz clock), and asynchronous interfaces via GPMC with BCH-based ECC (4/8/16-bit per 512-byte block); power management includes DVFS, five ADPLLs for domain-specific clock generation, and RTC with independent 32.768-kHz oscillator and battery-backed wake capability.

Key Specifications

Pinout & Package

AMIC120BZDNA30 uses a 491-ball NFBGA (ZDN suffix) package with 0.65-mm ball pitch and via-channel array technology optimized for low-cost routing in industrial control PCBs. Pin functions are defined across nine ball map sections (Tables 4-1 to 4-9), supporting full signal access to all integrated peripherals.

FAQ

What is the maximum operating frequency of the ARM Cortex-A9 core in the AMIC120BZDNA30?

The AMIC120BZDNA30 features an ARM Cortex-A9 processor core rated for operation up to 300 MHz. This frequency is validated under specified thermal and voltage conditions per TI's SPRSP09B datasheet, and enables execution of Linux-based real-time applications with sufficient margin for deterministic interrupt latency in industrial control loops. The AMIC120BZDNA30 does not support dynamic overclocking beyond this specification.

Does the AMIC120BZDNA30 support LPDDR2 memory, and what is the maximum data rate?

Yes, the AMIC120BZDNA30 supports LPDDR2 memory with a maximum clock frequency of 266 MHz, corresponding to a data rate of LPDDR2-533. This is implemented via its 32-bit EMIF interface and is fully supported in TI's Processor SDK for Linux and RTOS environments. The AMIC120BZDNA30 also supports DDR3 and DDR3L at 400-MHz clock (DDR-800 data rate).

How many PRU-ICSS subsystems does the AMIC120BZDNA30 include, and what protocols do they support?

The AMIC120BZDNA30 includes two PRU-ICSS subsystems - PRU-ICSS0 and PRU-ICSS1 - each with dual 200-MHz PRU cores and dedicated RAM. These subsystems natively support EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, EnDat 2.2, and other industrial protocols via TI's PRU-ICSS Ethernet Protocol Stack (PRU-ICSS-EP). The AMIC120BZDNA30 can run multiple protocols concurrently, such as EtherCAT on PRU-ICSS0 and EnDat 2.2 on PRU-ICSS1.

What ADC resolution and sampling rate does the AMIC120BZDNA30 provide?

The AMIC120BZDNA30 integrates two independent 12-bit successive approximation register (SAR) ADCs - ADC0 and ADC1 - each capable of up to 867 kSPS. Each ADC supports eight analog inputs via an internal 8:1 analog multiplexer, and both share common reference pins (VREFP/VREFN). This ADC performance is sufficient for motor current sensing, temperature monitoring, and analog I/O in industrial edge devices using the AMIC120BZDNA30.

Is the AMIC120BZDNA30 pin-compatible with other AMIC120 variants such as AMIC110 or AM437x?

No, the AMIC120BZDNA30 is not pin-compatible with AMIC110 or AM437x devices. While it shares the same 491-ball ZDN package footprint with AMIC110BZDNA30, functional pin assignments differ significantly - particularly for PRU-ICSS, EMAC, and ADC signals. The AM437x family uses different package types (e.g., ABZ, ABA) and has incompatible ball maps. Board-level reuse requires verification against TI's ZDN ball maps for each specific part number.
