FAQ
What is the maximum operating frequency of each core in the AD21584WCBCZ4A10?
The AD21584WCBCZ4A10 operates its two SHARC+ cores at up to 500 MHz each and its Arm Cortex-A5 core at up to 500 MHz. These frequencies are guaranteed across the full AEC-Q100 Grade 1 temperature range (−40°C to +125°C) with appropriate voltage and cooling. All timing specifications in the datasheet assume these maximum speeds.
Does the AD21584WCBCZ4A10 support secure boot and cryptographic acceleration?
Yes, the AD21584WCBCZ4A10 includes hardware cryptographic accelerators (AES-128/256, SHA-256, RSA) and supports fast secure boot with on-chip OTP memory for key storage. It also implements Arm TrustZone to isolate secure world execution, enabling trusted firmware updates and IP protection-key features validated for automotive security requirements.
How many CAN 2.0 interfaces does the AD21584WCBCZ4A10 integrate, and what is their bit-rate capability?
The AD21584WCBCZ4A10 integrates two independent CAN2.0 controllers, each supporting bit-rates up to 1 Mbps and compliant with ISO 11898-1. Each controller has dedicated message RAM, filtering, and loopback modes, allowing simultaneous operation on separate vehicle networks (e.g., powertrain CAN and body CAN) without software arbitration overhead.
What type of on-chip memory does the AD21584WCBCZ4A10 provide for the SHARC+ cores?
Each SHARC+ core in the AD21584WCBCZ4A10 has 5 Mb (640 kB) of L1 SRAM with parity protection. This memory is configurable as instruction/data SRAM or cache, and supports single-cycle access at full core speed. Additionally, the device provides 256 kB of shared L2 SRAM with ECC and 512 kB of L2 ROM for boot code and libraries.
Is the AD21584WCBCZ4A10 pin-compatible with other members of the ADSP-2158x family?
No, the AD21584WCBCZ4A10 is not pin-compatible with AD21583WCBCZ4A10 or AD21587 variants due to differences in peripheral mapping and ball function allocation-even though all use the same 349-ball CSP_BGA package. Pin assignments must be verified against the specific device's ball map in the ADSP-2158x datasheet Rev. C, Section "349-Ball CSP_BGA Signal Descriptions".
