NXP Semiconductors MIMX9312CVXXMAB

Overview

MIMX9312CVXXMAB from NXP Semiconductors is an industrial-grade applications processor featuring a single Arm® Cortex®-A55 core running at 1.7 GHz, a dual-core Arm® Cortex®-M33 real-time subsystem operating up to 250 MHz, and no integrated NPU. It supports LPDDR4X/LPDDR4 with inline ECC, delivers 3.2 GT/s DDR bandwidth, and integrates one Gigabit Ethernet controller with TSN support and one USB 2.0 interface - optimized for industrial HMI, energy metering, and touchless access control systems.

For engineers reviewing the MIMX9312CVXXMAB datasheet, MIMX9312CVXXMAB pinout, MIMX9312CVXXMAB application, or MIMX9312CVXXMAB equivalent, key selection considerations include its 9 × 9 mm FCBGA208 package, industrial temperature range (−40°C to +105°C), parallel camera/display interface support, and absence of neural processing hardware versus higher-tier i.MX 93 variants.

Technical Context

The MIMX9312CVXXMAB implements a heterogeneous compute architecture: the Cortex-A55 handles Linux-based application workloads while the dual Cortex-M33 cores manage deterministic real-time tasks, secure boot, and low-power monitoring - with independent power gating between domains. Its memory subsystem includes 640 KB on-chip RAM with ECC, 256 KB cluster L3 cache, and parity/ECC protection across L1/L2 caches and TLBs.

Connectivity is streamlined for edge gateway roles: one GbE controller with IEEE 1588/TSN, one USB 2.0 PHY, two FlexCAN modules (CAN-FD capable), eight LPUARTs, and three uSDHC interfaces supporting eMMC 5.1, SDXC, and SDIO - all routed through a centralized IOMUXC with GPIO interrupt capability and programmable pad control.

FAQ

What is the maximum operating frequency of the Cortex-A55 core in MIMX9312CVXXMAB?

The Cortex-A55 core in MIMX9312CVXXMAB operates at a maximum frequency of 1.7 GHz under industrial temperature conditions (−40°C to +105°C). This speed is guaranteed across the full junction temperature range and supported by the on-die PLL and thermal management circuitry documented in the IMX93IEC datasheet Rev. 8.

Does MIMX9312CVXXMAB include a Neural Processing Unit (NPU)?

No, MIMX9312CVXXMAB does not include an NPU. As confirmed in Table 2 of the IMX93IEC datasheet, this variant is explicitly marked "-" under the NPU column, distinguishing it from MIMX932x and MIMX935x variants which list "NPU". The absence of NPU reduces silicon area, power consumption, and software stack complexity.

What package type and pin count does MIMX9312CVXXMAB use?

MIMX9312CVXXMAB uses a 9 × 9 mm FCBGA208 package with 0.5 mm ball pitch. This is confirmed in Table 2 of the IMX93IEC datasheet and Figure 1's nomenclature guide, where "VX" denotes the 9 × 9 mm FCBGA208 variant - distinct from the larger 11 × 11 mm (VV) and 14 × 14 mm (VT) packages used by other i.MX 93 SKUs.

Which display and camera interfaces are supported by MIMX9312CVXXMAB?

MIMX9312CVXXMAB supports parallel camera input and parallel RGB display output only - as stated in Table 2 under "Camera" and "Display" columns. It does not support MIPI CSI-2, MIPI DSI, or LVDS interfaces, making it suitable for legacy or cost-optimized imaging/display subsystems without high-speed serial PHY overhead.

What is the DDR memory interface specification for MIMX9312CVXXMAB?

MIMX9312CVXXMAB implements a 16-bit LPDDR4X/LPDDR4 interface with inline ECC, supporting up to 2 GB of external DRAM and delivering 3.2 GT/s effective bandwidth. This is specified in Table 2 ("DDR" column) and Section 4.1.3 of the IMX93IEC datasheet, with voltage compliance defined for VDD2_DDR and VDDQ_DDR rails.
