System developers in many industries are finding RISC-V processors to be a smart and reliable alternative to previously popular microcontrollers and processors.
The RISC-V processors CAST offers build on our decades-long experience with thousands of microcontroller and processor IP customers.
We focus on competitive 32-bit solutions in key areas: Functional Safety and Ultra-Low Power. All these RISC-V processors feature:
- RISC-V ISA support that is extensive and configurable,
- High quality and exceptional reliability through best design and coding practices and rigorous verification and testing,
- Royalty-free and other flexible licensing options,
- Design for reusability with easy integration and complete deliverables, and
- Companion IP cores for bus fabrics, peripherals, networking, security, and hardware accelerators for compression.
Like all the IP cores we offer, these RISC-V processor cores are built to CAST's extremely high quality standards and are backed with industry-leading 24-hour support.
- A single-issue, in-order, 5-stage pipeline processor with an optional L0 instruction cache;
- Extensive RV32 base integer or base embedded ISA options, including full, partial, or optional support for RV32[I/E][C][M][F][D][A][Zicsr][Zifencei] and Vector Instructions;
- Fail-safe design features, including Dual Modular Redundancy (DMR) in Lockstep or triple (TMR), Error Correcting Code (ECC), and sample Reset and Safety Manager modules; and
- A complete ISO 26262 Certification Package, including a Safety Manual (SAM) and a Failure Modes, Effects and Diagnostics Analysis (FMEDA) document.

The performance and resource requirements of the EMSA5-FS vary with its configuration and ASIC or FPGA implementation. DMR versions start at 40k gates, and TMR at 60k. EMSA5-FS performance can readily exceed frequencies over 1GHz on advanced processor nodes.
The core's deliverbles include a Safety Manual (SAM), a Failure Modes, Effects and Diagnostics Analysis (FMEDA) document, and the ASIL-D Ready certificate issued by SGS-TÜV Saar GmbH. Reference designs on FPGA boards are available.
“Like Ubilite with Wi-Fi, CAST provides extremely compet-itive IP core products that are high-quality, complete, and easy to integrate and use,” said Peter Gammel, chief executive officer for Ubilite, Inc.. "We expect the RISC-V processor core we’ve licensed from CAST to help us maintain — and extend — the advantages of our low-power Wi-Fi SoCs over competing IoT products.” |
These 32-bit RISC-V low-power processors for embedded applications require a small silicon footprint for lower leakage and dynamic CPU power. They also employ advanced power management techniques such as dynamic clock gating and clock frequency scaling.
RISC-V support in these processors inludes RV32 base integer or base embedded ISA and extensions including full, partial, or optional support for RV32[I/E][C][M][F][D][A][N][Zicsr][Zifencei][Zc], with additional extensions available upon request.
The BA51 Ultra-Low-Power Deeply Embedded RISC-V Processor:
- has a single-issue, in-order, 2-stage pipeline;
- uses from 16K gates; and
- runs over 500 MHz (16nm) and achieves 400 Coremarks/MHz
- is optionally equipped with L0 instruction and data caches
The BA53 Low-Power Deeply Embedded RISC-V Processor:
- has a single-issue, in-order, 5-stage pipeline;
- uses from 30k gates; and
- runs over 1GHz (22nm) and achieves 2.53 Coremarks/MHz.
- is optionally equipped with L0 instruction and data cache
