CY8C3244LTI-161

Overview

The CY8C3244LTI-161 is an 8-bit microcontroller from the PSoC 3 family, utilizing the M8C core. It features 16 KB of Flash program memory and operates at a maximum clock frequency of 50 MHz. The device includes 2 kB of SRAM data memory and offers GPIO connectivity via a 48-QFN (7x7) package. It supports a supply voltage range of 1.71 V to 5.5 V and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a programmable analog block with a 12-bit Sigma-Delta ADC for high-resolution signal acquisition.
• Provides flexible digital logic resources through a configurable interconnect matrix for custom peripheral creation.
• Supports multiple communication interfaces including I2C, SPI, and UART for system connectivity.

Applications

• Industrial control systems requiring precise analog sensing
• Consumer electronics with low-power operation needs
• Embedded sensor interface modules

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for moisture sensitivity level requirements prior to surface-mount assembly. Ensure storage conditions meet specified humidity limits to prevent damage before reflow soldering processes are initiated.

Selection Notes

Select this component when an 8-bit architecture suffices for application logic while requiring integrated analog capabilities. Consider the 48-pin QFN footprint for space-constrained designs. Evaluate the 50 MHz processing speed against computational demands and verify that the available I/O count meets interface requirements without excessive external multiplexing.

Part Context

This part belongs to the Infineon PSoC 3 family, designed for mixed-signal applications. It combines a standard 8051-compatible processor with programmable analog and digital blocks. The series is known for reducing component count by integrating peripherals directly onto the silicon die compared to discrete solutions.
