NXP Semiconductors MCIMX503CVM8B

Overview

MCIMX503CVM8B from NXP Semiconductors (formerly Freescale) is an ARM Cortex-A8-based applications processor operating at 800 MHz, designed for portable multimedia systems with integrated 2D graphics acceleration (200 Mpix/s), eLCDIF display interface, and support for DDR2/LPDDR2/LPDDR1 DRAM up to 266 MHz. It omits the electrophoretic display controller (EPDC) but retains full GPU2Dv1, ePXP pixel pipeline, and dual USB 2.0 OTG/host PHYs - deployed in industrial HMI and e-reader control units.

For engineers reviewing the MCIMX503CVM8B datasheet, MCIMX503CVM8B pinout, MCIMX503CVM8B application, or MCIMX503CVM8B equivalent, key selection criteria include its 400-pin MAPBGA package (17 × 17 mm, 0.8 mm pitch), absence of EPDC hardware, support for 10/100 Ethernet, five UARTs, and secure boot via HAB4 with SHA-256 and 2048-bit RSA.

Technical Context

The MCIMX503CVM8B implements a 64-bit AXI fabric (266 MHz) as its central interconnect, aggregating ARM CPU, ePXP, eLCDIF, GPU2D, SDMA, FEC, and USB controllers. Its memory subsystem includes 32 KB L1 instruction cache, 32 KB L1 data cache, and 256 KB unified L2 cache, with external memory support spanning DDR2-533, LPDDR2-533, NAND Flash (with 32-bit ECC), and eMMC 4.4.

Power management leverages Smart Speed™ technology with dynamic voltage and frequency scaling (DVFS), state-retention power gating (SRPG) for ARM core and NEON, and four independent PLLs - one dedicated to display clocking with eight controllable outputs. Security is enforced via High-Assurance Boot 4 (HAB4), Secure JTAG Controller (SJC), and tamper-resistant SRTC.

Key Specifications

Pinout & Package

MCIMX503CVM8B uses a 400-ball MAPBGA package (Case 400), 17 × 17 mm, 0.8 mm pitch, RoHS-compliant and lead-free (MSL 3). Pin assignments follow the i.MX50 family ball map; EPDC-related pins are physically present but functionally disabled and must be configured via IOMUX to alternate functions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar applications processor applications.

Compared with MCIMX503CVM8B, MCIMX507CVM8B removes 2D graphics acceleration while preserving display interface and multimedia processing, whereas MCIMX502CVM8B further eliminates EPDC functionality - both retain identical 400-MAPBGA packaging and 800 MHz operation, enabling drop-in replacement only if GPU-dependent code is removed or replaced.

FAQ

What is the maximum operating frequency of the MCIMX503CVM8B?

The MCIMX503CVM8B operates at a maximum core frequency of 800 MHz. This is confirmed in Table 1 of the IMX50CEC datasheet (Rev. 7, Oct 2013), which lists MCIMX503CVM8B under the "800 MHz" column for Maximum ARM CLK Frequency. The device does not support 1 GHz operation - that capability is reserved for MCIMX508 and MCIMX507 variants.

Does the MCIMX503CVM8B include an electrophoretic display controller (EPDC)?

No, the MCIMX503CVM8B explicitly excludes the EPDC hardware block. As stated in Table 2 ("Part Number Feature Comparison") of the IMX50CEC datasheet, MCIMX503 disables the EPDC. While EPDC-related pins exist on the 400-MAPBGA package, they are functionally inactive and must be reassigned via IOMUX to alternate functions - unlike the MCIMX508 series which fully enables EPDC.

Which package type does the MCIMX503CVM8B use, and what are its key mechanical properties?

The MCIMX503CVM8B uses a 400-pin MAPBGA package (Case 400), measuring 17 × 17 mm with 0.8 mm ball pitch. Per Section 1.5 ("Package Feature Comparison") of the IMX50CEC datasheet, this variant deletes DRAM_SDCLK_1, DRAM_SDCLK_1_B, DRAM_A14, DRAM_SDODT1, UART2_CTS, and UART2_RTS versus the 416-MAPBGA, and keeps USB_OTG_VDDA25 and USB_H1_VDDA33 electrically independent - critical for low-noise USB PHY design.

What display interfaces are supported by the MCIMX503CVM8B?

The MCIMX503CVM8B supports the enhanced LCD Interface (eLCDIF), capable of driving SXGA+ (1400 × 1050) displays at 60 Hz with up to 32-bit parallel RGB output. It does not support the Electrophoretic Display Controller (EPDC), as confirmed in Table 2. The eLCDIF operates synchronously with the ePXP pixel pipeline, allowing on-chip SRAM buffering of processed frames - enabling smooth UI transitions and video overlays without external frame buffers.

How does the MCIMX503CVM8B implement hardware security for firmware integrity?

The MCIMX503CVM8B implements High-Assurance Boot 4 (HAB4) with SHA-256 hashing, 2048-bit RSA signature verification, version control, and warm boot support - ensuring only cryptographically signed firmware images execute. This is complemented by a Secure JTAG Controller (SJC) that blocks unauthorized debug access and a tamper-resistant Secure RTC (SRTC). All security features are active and identical to those in higher-tier i.MX50 variants, as confirmed in Sections 1.1.8 and 6 of the IMX50CEC datasheet.
