21281CB

The 21281CB is a single-core SA-110 microprocessor IC delivering 32-bit processing at 200 MHz in a compact 144-TQFP (20×20) surface-mount package. Designed for embedded applications, it integrates support for SDRAM and SRAM memory controllers and targets commercial-grade systems with an operating temperature range of 0 °C to 70 °C.

With 2.1 V I/O and a standardized 144-pin LQFP footprint, the 21281CB is suited for space-constrained embedded designs that require a known SA-110 architecture and reliable, vendor-supported silicon from Intel.

Key Features

• Core  SA-110 single-core, 32-bit processor core running at 200 MHz for deterministic embedded processing.
• Memory  Integrated controllers for SDRAM and SRAM to support common external memory configurations.
• I/O Voltage  2.1 V I/O specification for compatibility with low-voltage system interfaces.
• Package & Mounting  144-TQFP (20×20) / 144-LQFP package in a surface-mount form factor for compact PCB designs.
• Operating Range & Grade  Commercial grade device with an operating temperature range of 0 °C to 70 °C.
• Manufacturer  Intel-supplied device from the i21281 series, RoHS compliant for environmental regulations.

Typical Applications

• Embedded control systems  Use the 21281CB for general-purpose control tasks and deterministic processing in embedded products.
• Memory-driven designs  Systems that require SDRAM or SRAM interfacing benefit from the on-chip memory controller support.
• Compact electronics  The 144-TQFP surface-mount package fits space-constrained PCBs and module-based assemblies.
