CYPM1116-48LQXIT

Application Specific Microcontrollers Overview

The CYPM1116-48LQXIT is a programmable system-on-chip (PSoC) microcontroller from Infineon Technologies, belonging to the PSoC 3 family. It integrates an 8051-compatible CPU core with extensive analog and digital peripheral resources on a single chip. The device features up to 256 KB of Flash memory and 32 KB of SRAM, providing sufficient storage for complex embedded applications. Key specifications include a maximum operating frequency of 50 MHz and support for multiple communication interfaces such as SPI, I2C, and UART. The component is housed in a 48-pin LQFP package, designed for industrial temperature ranges, making it suitable for versatile control tasks requiring mixed-signal processing capabilities.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'IT' indicates the industrial temperature range grade when sourcing. Confirm the package type matches the 48-pin LQFP requirement for PCB layout compatibility. Check current product status as older PSoC 3 generations may have end-of-life implications for long-term production runs. Ensure supply chain stability by reviewing distributor availability for this specific part number variant.

Application Specific Microcontrollers Selection Notes

Select this model when an application requires significant analog signal conditioning alongside digital logic processing within a single MCU. Compare against PSoC 4 or 5 LP families if lower power consumption or ARM Cortex-M cores are preferred over the legacy 8051 architecture. Evaluate pin count requirements carefully, as the 48-pin package limits available I/O compared to larger packages in the same series. Consider development tool compatibility with Cypress/Infineon PSoC Creator software for peripheral configuration.

Application Specific Microcontrollers Part Context

This component belongs to the PSoC 3 family, which was designed to bridge the gap between discrete analog/digital solutions and standard microcontrollers. It succeeded earlier PSoC 1 devices and preceded the ARM-based PSoC 4 and 5 LP lines. The PSoC 3 series remains relevant for applications leveraging its unique analog routing matrix and established 8051 ecosystem, particularly in cost-sensitive industrial and consumer markets where proven reliability is prioritized over cutting-edge processor performance.

Application Specific Microcontrollers Replacement Considerations

Direct pin-to-pin replacements within the PSoC 3 family include other 48-pin variants like CY8C32666 or CY8C32678, depending on memory size needs. For architectural upgrades, consider PSoC 4100 Plus or PSoC 5LP equivalents, though these require schematic and firmware redesign due to different CPU cores and peripheral sets. Verify that any substitute maintains the required voltage levels and interface speeds for the existing system design.
