NXP Semiconductors MCIMX502CVK8B

Overview

MCIMX502CVK8B from NXP Semiconductors (formerly Freescale) is an ARM Cortex-A8-based applications processor operating at 800 MHz, designed for cost-optimized portable multimedia systems. It integrates a 256 KB L2 cache, dual eCSPI interfaces (66 Mbps), five UARTs (up to 4.0 Mbps), and a 10/100 Ethernet controller. The device supports DDR2/LPDDR2/LPDDR1 DRAM up to 266 MHz and includes hardware-accelerated NAND flash ECC (32-bit correction over 1 KB blocks), targeting embedded consumer devices with constrained BOM.

For engineers reviewing the MCIMX502CVK8B datasheet, MCIMX502CVK8B pinout, MCIMX502CVK8B application, or MCIMX502CVK8B equivalent, key selection considerations include its absence of GPU and EPDC blocks, 13 × 13 mm 416-pin MAPBGA package with 0.5 mm pitch, DVFS-enabled power management, and support for eMMC 4.4 via dedicated SD3 port - all critical for industrial HMI, smart metering, and low-cost display terminals.

Technical Context

The MCIMX502CVK8B implements a 64-bit AXI fabric (266 MHz) as its central interconnect, aggregating ARM CPU, ePXP, SDMA, FEC, and GPU2Dv1 masters to memory and peripherals. Its memory subsystem includes 32 KB L1 instruction and data caches, unified 256 KB L2 cache, 96 KB boot ROM with HAB4 security, and 128 KB on-chip RAM.

Power management relies on 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 providing eight controllable outputs for display and connectivity clock domains. Security features include High-Assurance Boot 4 (SHA-256, 2048-bit RSA), secure JTAG controller (SJC), and tamper-resistant SRTC.

Key Specifications

Pinout & Package

MCIMX502CVK8B uses a 13 × 13 mm, 0.5 mm pitch, 416-ball MAPBGA package (Case 416). Ball assignments follow the i.MX50 family pinout with full IOMUX flexibility; EPDC and GPU pins are physically present but functionally disabled.

Compared with MCIMX503CVK8B and MCIMX507CVK8B, the MCIMX502CVK8B provides the lowest-cost entry point into the i.MX50 family for non-graphic-intensive, non-e-paper applications - retaining full peripheral compatibility (UART, eCSPI, FEC, eSDHC) while removing two major IP blocks to reduce silicon area and leakage current.

Availability

MCIMX502CVK8B is available at Aetrix Electronics and suitable for industrial HMI, smart energy metering, retail digital signage, and medical patient monitoring requiring stable component supply across extended product lifecycles.

Supply support for MCIMX502CVK8B includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

NXP Semiconductors is a global semiconductor company formed from the spin-off of Philips' semiconductor division, now headquartered in Eindhoven, Netherlands, with leadership in secure connectivity and edge processing solutions.

The i.MX50 family was developed by Freescale (acquired by NXP in 2015) to deliver energy-efficient, multimedia-capable applications processors for portable consumer electronics - with MCIMX502CVK8B specifically optimized for cost-sensitive, display-optional embedded systems.

FAQ

What is the maximum operating frequency of the MCIMX502CVK8B?

The MCIMX502CVK8B is rated for a maximum ARM Cortex-A8 core frequency of 800 MHz under industrial temperature conditions (0°C to 70°C ambient). This frequency is achieved with appropriate voltage scaling and thermal management; it does not support the 1 GHz option found in MCIMX508 variants. The 800 MHz target enables lower power consumption and reduced thermal design complexity compared to higher-speed derivatives.

Does the MCIMX502CVK8B include a GPU or EPDC block?

No, the MCIMX502CVK8B explicitly excludes both the GPU2Dv1 graphics accelerator and the Electrophoretic Display Controller (EPDC). These blocks are disabled in silicon per the N78A mask set, distinguishing it from MCIMX508 and MCIMX503 variants. However, the physical pins remain present and can be reused via IOMUX configuration for alternate functions such as GPIO or additional UART signals.

Which memory types does the MCIMX502CVK8B support?

The MCIMX502CVK8B supports DDR2-533, LPDDR2-533, and LPDDR1-400 DRAM up to 2 GB total capacity, plus NAND Flash (SLC/MLC) with hardware BCH32 ECC, NOR Flash, PSRAM, Cellular RAM, and managed NAND including eMMC 4.4. It does not support DDR3 or LPDDR3, and its DRAM controller is limited to 266 MHz clock rates per JEDEC specification.

What package type is used for the MCIMX502CVK8B?

The MCIMX502CVK8B uses a 13 × 13 mm, 0.5 mm pitch, 416-ball MAPBGA package (Case 416). This RoHS-compliant, lead-free package has Moisture Sensitivity Level 3 and shares pinout compatibility with other i.MX50 416-ball variants like MCIMX508CVK1B and MCIMX507CVK1B, enabling layout reuse across performance tiers.

How does the MCIMX502CVK8B handle secure boot and firmware authentication?

The MCIMX502CVK8B implements High-Assurance Boot 4 (HAB4) in its boot ROM, verifying signed firmware images using SHA-256 hashing and 2048-bit RSA public-key cryptography. It supports version control, warm boot, and tamper-resistant fuse programming. While the GPU and EPDC are disabled, HAB4 remains fully functional and is unaffected by those feature omissions.
