1. Core & Memory:
️· Internal RAM: 128 Kbytes - Can be split between Secure and Non-Secure RAM.
️· Boot ROM: 36 Kbytes – Supports secure and regular boot modes.
2. Security Features:
️· SAHARA Lite: Security co-processor: AES, DES, 3DES, RC4 encryption, MD5, SHA-1, SHA-224, SHA-256 hashing, and a hardware random number generator.
️· RTIC (Real-Time Integrity Checker): Monitors memory content for corruption during operation.
️· IIM (IC Identification Module): Handles fuse elements, chip identifiers, cryptographic keys, JTAG secure mode, and control signals.
️· SCC (Security Controller): Securely holds sensitive data (keys, DRM keys, passwords) and erases data if access is deemed insecure. Has a Key Encryption Module (KEM).
️· SIM (Subscriber Identity Module Interface): Asynchronous interface for Smart Cards (ISO 7816).
3. I/O & Connectivity:
️· I2C: Two standard I2C ports (up to 400 Kbps). HS-I2C (up to 3.4 Mbps) - *Note:* See errata for HS-I2C.
️· PWM: Pulse Width Modulator (16-bit counter), used for sound generation and tone generation.
️· Keypad Port (KPP): 8x8 external keypad matrix.
️· P-ATA: Parallel ATA host interface (AT Attachment). Muxed with eSDHC-4 interfaces.
️· SDMA: Smart Direct Memory Access - A flexible DMA engine with multiple channels and features.
️· SIM: Subscriber Identity Module Interface
4. Display & Image Processing:
️· IPU (Image Processing Unit): For connecting to displays and image sensors, with image enhancement, video/graphics combining, and conversion capabilities.
️· PWM: Also utilized for sound generation, a key component for audio output.
5. System Control & I/O Multiplexing
️· IOMUXC: I/O Multiplexing Control - Allows flexible assignment of functions to I/O pins.
️· SDMA: Smart Direct Memory Access - Used for DMA transfers and managing memory access.
Key Notes & Considerations:
️· Errata: The text explicitly mentions checking the errata for the HS-I2C.
️· Muxed/Shared Resources: Several functions (P-ATA and eSDHC-4) are multiplexed (shared) on the same pins/resources.
️· Security: The i.MX51 has a strong focus on security features, with multiple modules dedicated to protecting data and code.
