CAST, Inc. 8051 Microcontroller IP
IP Cores and Subsystems for a Faster Time to Market.
Overview
CAST, Inc. provides a family of 8051-compatible microcontroller cores that are among the most popular and widely-used 8-bit CPUs for embedded systems. These cores range from extremely small, low-power versions to high-performance variants that execute instructions much faster than the original 8051. They are a popular choice for control functions in larger SoCs or as the main processor in smaller embedded devices due to their small size, low power, and mature toolchain.
✨ Key Features
- 8051/80251 instruction set compatible
- Highly configurable (timers, UARTs, I/O ports)
- From ultra-low power to high-performance versions
- Optional peripherals and on-chip debug capabilities
- Royalty-free licensing model
🎯 Key Differentiators
- Broad range of 8051 cores from a trusted, long-standing vendor
- Attractive royalty-free business model
- Focus on quality and customer support
Unique Value: Provides a reliable, cost-effective, and easy-to-use 8-bit microcontroller solution for embedded control tasks, backed by a mature ecosystem and a straightforward business model.
