Does the MCF51JM64VLK include cryptographic acceleration hardware?
Yes, the MCF51JM64VLK includes a Cryptographic Acceleration Unit (CAU) that offloads DES, 3DES, AES, MD5, and SHA-1 operations from the CPU, and a Random Number Generator Accelerator (RNGA) compliant with FIPS-140. These modules are present in the VLK variant (non-E suffix), as confirmed in Table 1 of the MCF51JM128 datasheet, which lists CAU+RNGA as standard across all JM64 configurations including MCF51JM64VLK.
What package and pin count does the MCF51JM64VLK use?
The MCF51JM64VLK uses an 80-pin LQFP package measuring 14 mm × 14 mm, with lead pitch of 0.5 mm. This is explicitly stated in Table 3 ("Orderable Part Number Summary") of the MCF51JM128 datasheet, where "MCF51JM64VLK" is listed with "80 LQFP" under the Package column. Pin assignments match the 80-pin LQFP diagram in Figure 2 and Table 4.
How many CAN channels does the MCF51JM64VLK support?
The MCF51JM64VLK supports one Controller Area Network (CAN) channel via its MSCAN module, compliant with CAN 2.0A/B protocol. As shown in Table 1 ("Device Comparison"), all JM64 variants - including MCF51JM64VLK - list "Yes" under the CAN row. The module provides five receive buffers, three transmit buffers, and programmable wakeup filtering, enabling robust automotive and industrial network node functionality.
Is USB On-The-Go functionality available on the MCF51JM64VLK?
Yes, the MCF51JM64VLK integrates a full-speed USB On-The-Go (USBOTG) dual-role controller, supporting both device and host modes per USB 2.0 specification. It includes an on-chip transceiver, 3.3 V regulator, and pull-up resistors - eliminating external components. This capability is confirmed in the "Functional Units" table (Table 2) and Section 1.3.1 of the datasheet, and applies to all JM64 variants including MCF51JM64VLK.
