Infineon Technologies CY8C20336H-24LQXIT

Overview

CY8C20336H-24LQXIT from Cypress Semiconductor is a haptics-enabled CapSense® programmable mixed-signal controller featuring an M8C 8-bit Harvard-architecture CPU (up to 24 MHz), 8 KB flash / 1 KB SRAM, integrated Immersion TS2000 ERM haptics driver, and configurable capacitive sensing for up to 28 GPIOs in a 24-pin QFN package. It operates from 1.71 V to 5.5 V across –40 °C to +85 °C and supports touch buttons, sliders, and proximity sensing in consumer HMI applications.

For engineers reviewing the CY8C20336H-24LQXIT datasheet, CY8C20336H-24LQXIT pinout, CY8C20336H-24LQXIT application, or CY8C20336H-24LQXIT equivalent, key selection criteria include its integrated CapSense analog block with SmartSense™ auto-tuning, TS2000 haptics control with 14 preloaded effects, dual-mode GPIO (digital/analog), and I²C slave interface operating at 400 kHz with hardware address validation.

Technical Context

The device integrates a dedicated CapSense analog subsystem-including programmable IDACs, comparators, and CSCLK timing-capable of autonomous capacitive scan without CPU intervention. Its M8C core executes firmware while managing real-time sensor polling and haptics waveform generation via the TS2000 controller block.

System-level timing is governed by multiple synchronized clocks: a ±5% 6/12/24 MHz internal main oscillator (IMO), a 32-kHz internal low-speed oscillator (ILO) for sleep/wake, and optional precision 32-kHz external crystal support. All GPIOs support hot-swap capability and configurable drive modes (CMOS, open-drain, pull-up, high-Z) with 25-mA sink per pin.

FAQ

Does CY8C20336H-24LQXIT support I²C master mode?

No. The device implements I²C slave-only functionality with hardware address validation and 32-byte RAM buffer interface. It cannot initiate I²C transactions or act as a bus master. External communication must be driven by a master controller, such as an application MCU or SoC.

Can SmartSense™ be disabled for manual CapSense tuning?

Yes. SmartSense™ is firmware-configurable and can be disabled via PSoC Designer™ or direct register writes. Disabling it allows full manual control over baseline update rate, finger threshold, and noise filters - required for specialized applications like wet-touch or ultra-low-power periodic scan.

What is the maximum ERM motor drive capability of the TS2000 block?

The integrated TS2000 haptics controller supports up to three ERM modules with peak drive current limited by GPIO sink capability: 25 mA per pin, 120 mA total. Motor selection must comply with these limits and the 1.8–5.5 V supply range; typical 3 V, 80 mA RMS motors operate reliably with appropriate current-limiting resistors.

Is the 24-pin QFN package RoHS-compliant and halogen-free?

Yes. The CY8C20336H-24LQXIT uses a lead-free, RoHS-compliant 24-pin QFN package with halogen-free molding compound, meeting IPC/JEDEC J-STD-020D reflow profile requirements and certified to JEDEC Level 3 moisture sensitivity.
