Texas Instruments AMIC110BZCZA

Overview

AMIC110BZCZA from Texas Instruments is a programmable industrial communications SoC built around a 300-MHz ARM Cortex-A8 processor with NEON SIMD coprocessor, 32KB L1 instruction and 32KB L1 data cache (with parity), 256KB L2 cache (with ECC), and dual 200-MHz PRU-ICSS subsystems supporting EtherCAT, PROFINET, and EtherNet/IP. It integrates dual Gigabit Ethernet MACs with switch, two USB 2.0 DRD ports, two CAN 2.0B controllers, and an 8-channel 12-bit SAR ADC - deployed in industrial I/O modules and connected drives.

For engineers reviewing the AMIC110BZCZA datasheet, AMIC110BZCZA pinout, AMIC110BZCZA application, or AMIC110BZCZA equivalent, key selection considerations include PRU-ICSS real-time protocol offload capability, DDR3/DDR2/mDDR memory interface support, IEEE 1588v1 PTP timing accuracy, industrial temperature range (–40°C to 105°C), and 324-ball NFBGA package compatibility with PCB layout for high-speed signal integrity.

Technical Context

The AMIC110BZCZA implements a heterogeneous architecture: the Cortex-A8 MPU subsystem handles high-level OS tasks (Linux, TI-RTOS), while the independent PRU-ICSS executes deterministic real-time protocols without CPU intervention. Its EMIF supports DDR3 at 400 MHz clock (800 Mbps data rate) and GPMC enables NAND/NOR flash with 4-/8-/16-bit BCH ECC.

Power management uses SmartReflex Class 2B adaptive voltage scaling and five ADPLLs for precise clock generation across domains - MPU, DDR, USB, and peripherals - with dedicated RTC power domain and external wake-up capability via EXT_WAKEUP pin.

Key Specifications

Pinout & Package

FAQ

What is the maximum DDR3 data rate supported by the AMIC110BZCZA?

The AMIC110BZCZA supports DDR3 at a 400-MHz clock frequency, delivering an 800-Mbps data rate on its 16-bit bus. This is confirmed in Section 1.1 of the SPRS971D datasheet under External Memory Interfaces, and applies directly to the AMIC110BZCZA ZCZ package variant. The controller also supports DDR2 (532 Mbps) and mDDR (400 Mbps).

Does the AMIC110BZCZA include hardware support for IEEE 1588 Precision Time Protocol?

Yes, the AMIC110BZCZA implements IEEE 1588v1 Precision Time Protocol (PTP) with hardware timestamping in both Ethernet MACs. As documented in Section 1.1 and Table 3-1 of SPRS971D, this enables sub-100 ns timestamp accuracy for time-synchronized industrial automation - a feature retained in all AMIC110 variants including AMIC110BZCZA.

Can the PRU-ICSS in the AMIC110BZCZA run EtherCAT slave firmware independently of the Cortex-A8 core?

Yes, the dual PRU-ICSS subsystem in the AMIC110BZCZA executes EtherCAT slave protocol stacks autonomously at 200 MHz, with dedicated 8KB instruction RAM, 8KB data RAM, and 12KB shared RAM. This is explicitly stated in the "Programmable Real-Time Unit Subsystem" section of SPRS971D and verified for AMIC110BZCZA in TI's Industrial SDK documentation.

What analog input capabilities does the AMIC110BZCZA provide?

The AMIC110BZCZA integrates an 8-channel, 12-bit SAR ADC capable of 200 kSPS sampling, with inputs AIN0–AIN7 routed through an internal 8:1 analog multiplexer. This configuration is specified in Section 1.1 and Table 3-1 of SPRS971D and applies identically to the AMIC110BZCZA part number.

Is the AMIC110BZCZA qualified for operation at 105°C ambient temperature?

Yes, the AMIC110BZCZA is rated for operation from –40°C to +105°C ambient temperature, as confirmed in Table 3-1 of SPRS971D under "Operating temperature range". This qualification covers all electrical specifications and thermal performance across the full voltage and frequency operating points defined for the ZCZ package.
