NXP Semiconductors MCIMX508CVM8BR2

Overview

MCIMX508CVM8BR2 from NXP Semiconductors (formerly Freescale) is a high-performance ARM Cortex-A8 applications processor optimized for portable multimedia and e-paper systems. It operates at 800 MHz, integrates an Electrophoretic Display Controller (EPDC), 2D GPU (200 Mpix/s), ePXP pixel pipeline, and supports LPDDR2/DDR2 up to 266 MHz. It targets low-power consumer electronics requiring dual-display capability with grayscale EPD and LCD support.

For engineers reviewing the MCIMX508CVM8BR2 datasheet, MCIMX508CVM8BR2 pinout, MCIMX508CVM8BR2 application, or MCIMX508CVM8BR2 equivalent, key selection criteria include EPDC availability, 400-pin MAPBGA 17×17 mm 0.8 mm pitch package compatibility, dual-display timing constraints, and HAB4-secured boot requirements in battery-constrained embedded designs.

Technical Context

The MCIMX508CVM8BR2 implements a 64-bit AXI fabric (266 MHz) as its central interconnect, aggregating ARM CPU, EPDC, eLCDIF, GPU2D, ePXP, SDMA, and DRAM controller access to on-chip RAM, ROM, and external memory. Its QoS controller dynamically prioritizes display traffic between EPDC and eLCDIF to maintain real-time refresh integrity.

It features four PLLs - including a dedicated display PLL with eight independently controllable outputs - enabling precise clock domain isolation for EPD panel timing (e.g., 106 Hz @ 2048×1536) and LCD interface synchronization. Power management includes DVFS, SRPG for ARM/NEON, and on-chip 32 kHz/24 MHz oscillators.

Key Specifications

Pinout & Package

MCIMX508CVM8BR2 uses the 400-pin MAPBGA package (Case 400), 17 × 17 mm, 0.8 mm pitch. This package omits DRAM_SDCLK_1, DRAM_SDCLK_1_B, DRAM_A14, DRAM_SDODT1, UART2_CTS, and UART2_RTS versus the 416-pin variant, and provides independent USB_OTG_VDDA25/USB_H1_VDDA25 and USB_OTG_VDDA33/USB_H1_VDDA33 supplies.

FAQ

What display interfaces does the MCIMX508CVM8BR2 support?

The MCIMX508CVM8BR2 supports two concurrent display interfaces: the Electrophoretic Display Controller (EPDC) for E Ink® panels and the enhanced LCD Interface (eLCDIF) for standard LCDs. When both are active, eLCDIF operates in 16-bit mode due to pin multiplexing. EPDC supports resolutions up to 4096×4096 at 20 Hz or 2048×1536 at 106 Hz, while eLCDIF handles beyond SXGA+ (1400×1050) at 60 Hz. These capabilities are confirmed in the i.MX50CEC datasheet Rev. 7, Section 1.1.3.

Does the MCIMX508CVM8BR2 include hardware security features?

Yes, the MCIMX508CVM8BR2 includes Advanced High-Assurance Boot 4 (HAB4) with SHA-256 hashing and 2048-bit RSA signature verification, a Secure JTAG Controller (SJC) to prevent debug port attacks, and a tamper-resistant Secure Real-Time Clock (SRTC). These features enable secure firmware authentication and protect against unauthorized access - critical for medical and payment applications. All are documented in Section 1.1.8 and Table 4 of the i.MX50CEC datasheet.

What memory types does the MCIMX508CVM8BR2 support?

The MCIMX508CVM8BR2 supports DDR2-533, LPDDR2-533, and LPDDR1-400 DRAM (up to 2 GB total), plus 8-bit NAND Flash with 32-bit ECC per 1 KB block, 16/32-bit NOR Flash, PSRAM, Cellular RAM, and managed NAND including eMMC 4.4. The DRAM controller operates at up to 266 MHz clock rate. These specifications are verified in Section 1.1.5 and Table 4 of the i.MX50CEC datasheet Rev. 7.

Is the MCIMX508CVM8BR2 pin-compatible with other i.MX50 variants?

No - the MCIMX508CVM8BR2 uses the 400-pin MAPBGA package (17×17 mm, 0.8 mm pitch), which has different pin assignments and deleted signals (e.g., DRAM_A14, UART2_RTS) compared to the 416-pin MAPBGA/PoPBGA variants. While ball maps are consistent within the same package type, cross-package compatibility is not supported. This is explicitly stated in Table 3 (Package Feature Comparison) of the i.MX50CEC datasheet.

What is the operating temperature range for the MCIMX508CVM8BR2?

The MCIMX508CVM8BR2 is rated for ambient temperature from 0°C to 70°C and junction temperature from 0°C to 90°C. This industrial-grade specification is defined in Table 1 (Ordering Information) of the i.MX50CEC datasheet Rev. 7 and applies to all MCIMX508xxx part numbers in the MAPBGA 400 package configuration.
