NXP Semiconductors MCIMX7S5EVM08SD

Overview

MCIMX7S5EVM08SD from NXP Semiconductors is an industrial-grade heterogeneous applications processor featuring dual-core Arm Cortex-A7 (800 MHz) and Arm Cortex-M4, integrated 512 KB L2 cache, dual 12-bit ADCs, two CAN 2.0B interfaces, and Gigabit Ethernet with IEEE 1588 AVB support - deployed in smart HMI, access control panels, and portable medical devices.

For engineers reviewing the MCIMX7S5EVM08SD datasheet, MCIMX7S5EVM08SD pinout, MCIMX7S5EVM08SD application, or MCIMX7S5EVM08SD equivalent, key selection criteria include industrial temperature range (–20 to +105°C), 19×19 mm 0.75 mm pitch BGA package, TrustZone-enabled security architecture, and dual-ADC + dual-CAN configuration for deterministic real-time I/O.

Technical Context

The MCIMX7S5EVM08SD implements a tightly coupled heterogeneous architecture: the Cortex-A7 core runs Linux/Android with NEON MPE and 512 KB unified L2 cache, while the Cortex-M4 handles real-time tasks via 64 KB TCM and MPU-protected memory space. Both cores share boot ROM (96 KB HAB), 256 KB OCRAM, and SNVS-secured non-volatile storage.

Its system-level integration includes dedicated hardware accelerators (PXP for pixel processing, CAAM for cryptographic operations), dual-channel 12-bit ADCs (ENOB 9–10 bits), and full-featured connectivity: GbE with AVB, two FlexCAN controllers, MIPI-CSI/DSI, parallel LCDIF, and three uSDHC ports supporting HS400/eMMC.

FAQ

What is the maximum operating temperature specification for MCIMX7S5EVM08SD?

The MCIMX7S5EVM08SD is rated for industrial operation from –20°C to +105°C junction temperature, validated for continuous 10-year field life at full duty cycle. This specification is defined in Table 1 of the IMX7SCEC datasheet Rev. 7 and applies specifically to the 19×19 mm BGA variant with industrial qualification tier.

Does MCIMX7S5EVM08SD support secure boot, and how is it implemented?

Yes, MCIMX7S5EVM08SD implements High Assurance Boot (HABv4) with SHA-256 hashing, 2048-bit RSA signature verification, SRK revocation, and TrustZone initialization. Boot images are authenticated against eFUSE-programmed keys stored in the CSU, and execution proceeds only if signatures match - a feature confirmed in Section 1.2 and Security Reference Manual documentation.

How many ADC channels does MCIMX7S5EVM08SD provide, and what is their resolution?

MCIMX7S5EVM08SD integrates two independent 12-bit analog-to-digital converters (ADC1 and ADC2), providing eight total single-ended input channels. Effective number of bits (ENOB) is typically 9–10 bits depending on power/ground noise conditions, as specified in Section 4.11 of the IMX7SCEC datasheet Rev. 7.

What Ethernet capabilities does MCIMX7S5EVM08SD offer?

MCIMX7S5EVM08SD includes one Gigabit Ethernet controller (ENET1) supporting 10/100/1000 Mbps operation, IEEE 1588-2008 time synchronization, and Audio Video Bridging (AVB) features. It requires an external PHY and supports hardware timestamping, priority-based queuing, and precise packet scheduling for deterministic networking.

Is MCIMX7S5EVM08SD pin-compatible with other i.MX 7Solo variants like MCIMX7S5EVK08SD?

No, MCIMX7S5EVM08SD is not pin-compatible with MCIMX7S5EVK08SD. The former uses a 19×19 mm 0.75 mm pitch BGA (484 pins), while the latter uses a 12×12 mm 0.4 mm pitch BGA (364 pins). Pin counts, pitch, and signal mapping differ significantly - PCB redesign is required for substitution.
