CY8C20336AN-24LQXI

Application Specific Microcontrollers Overview

The CY8C20336AN-24LQXI is a Cypress Semiconductor PSoC 1 programmable system-on-chip featuring an M8C CPU core operating at up to 24 MHz. It integrates 8 KB of Flash memory and 1 KB of SRAM within a 24-pin QFN package. The device supports a supply voltage range of 1.71 V to 5.5 V and operates between -40 °C and +85 °C. Key capabilities include SmartSense auto-tuning for capacitive sensing, Full-Speed USB 2.0 compliance, I2C slave, SPI master/slave interfaces, three 16-bit timers, a 10-bit ADC, and two analog comparators.

Application Specific Microcontrollers Applications

• Capacitive touch button and slider interfaces requiring auto-tuning.
• USB-enabled human interface devices and peripherals.
• Low-power embedded controllers with analog signal acquisition needs.
• Systems requiring integrated I2C or SPI communication slaves.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'AN' against the official ordering guide to confirm package type and temperature grade. Confirm current availability status as product lifecycles may change. Ensure development tools like PSoC Designer are compatible with the selected silicon revision.

Application Specific Microcontrollers Selection Notes

Select this model when 8 KB Flash and 1 KB SRAM are sufficient for application firmware. Choose the 24-pin QFN package if board space constraints align with its dimensions. Verify that the required number of CapSense inputs fits within the 17 sensing inputs available on this specific package variant.

Application Specific Microcontrollers Part Context

This component belongs to the CY8C20XX6A/S family of 1.8 V Programmable CapSense Controllers. It shares architectural similarities with other members like the CY8C20337, differing primarily in memory size and pin count configurations within the same PSoC 1 ecosystem.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the same family include CY8C20336A variants with different suffixes indicating package or temperature changes. Cross-family migration to CY8C20xxxH or AS series requires verification of pin compatibility and feature parity.
