Infineon Technologies CY8C20336A-24LQXIT

Overview

CY8C20336A-24LQXIT from Cypress Semiconductor is a PSoC® 1 mixed-signal array IC configured with the TS2000 Haptics User Module for tactile feedback generation in capacitive touch interfaces. It integrates two 16-bit timers (Timer0 and Timer2) to generate 23 kHz PWM output and 5-ms haptic update intervals, operates at up to 3.3 V, and supports up to 14 Immersion TouchSense 2000 haptic effects for ERM actuators in handheld consumer devices.

For engineers reviewing the CY8C20336A-24LQXIT datasheet, CY8C20336A-24LQXIT pinout, CY8C20336A-24LQXIT application, or CY8C20336A-24LQXIT equivalent, key selection criteria include PWM frequency stability (≥22 kHz), 5-ms effect update timing tolerance (±10%), flash usage (15,922 bytes), RAM range (43–1803 bytes), and dual-timer resource allocation for concurrent haptic playback and host firmware execution.

Technical Context

The CY8C20336A-24LQXIT implements haptic feedback using firmware-driven timer resources: Timer_PWM generates ~23 kHz PWM output (FPWM = FClock / 255) with ≤90-clock-cycle ISR duration, while Timer_TMR provides precise 5-ms intervals (200 Hz update rate) for effect sequencing. Both timers operate from the IMO clock (recommended 24 MHz).

It requires external actuator drive circuitry (e.g., TPA6205A amplifier) and supports two ERM models: Sanyo NRS-2574i (≤150 g devices) and Jinlong Z6DL2A017000B (>150 g). Effect playback runs asynchronously-host code continues executing without blocking during haptic output.

Key Specifications

Pinout & Package

LQFP-24 package (7 mm × 7 mm, 0.4 mm pitch) with 18 GPIO pins, including dedicated routing for PWM output and amplifier enable signals. Pin assignment is configurable via PSoC Designer; default recommended outputs avoid P1[0]/P1[1] due to I2C conflict.

FAQ

What is the minimum clock source requirement for stable TS2000 operation on CY8C20336A-24LQXIT?

The device requires an internal main oscillator (IMO) clock of 24 MHz for guaranteed TS2000 timing compliance. The PWM input clock must be between 5.6 MHz and 13 MHz (derived from IMO via VC1 divider), yielding FPWM ≥22 kHz and EffectUpdateDivider in [109–255] range. Deviations cause out-of-spec haptic timing or waveform distortion.

Can CY8C20336A-24LQXIT drive piezoelectric actuators?

No. The TS2000 User Module and associated drive circuitry (TPA6205A) are characterized exclusively for Eccentric Rotating Motor (ERM) actuators-specifically Sanyo NRS-2574i and Jinlong Z6DL2A017000B. Piezo drivers require high-voltage, high-frequency AC waveforms incompatible with this implementation's 3.3 V DC-coupled PWM output.

How does disabling unused haptic effects impact memory usage?

Disabling effects directly reduces flash consumption: each enabled effect adds deterministic overhead to the 15,922-byte worst-case footprint. RAM usage also decreases-up to 1760 bytes saved-because effect-specific state buffers and lookup tables are excluded from linkage. Disabled effects cannot be invoked via TS2000_1_PlayEffect() API.

Is the 5-ms haptic update interval adjustable in firmware?

No-the 5-ms interval is fixed by the EffectUpdateDivider parameter calculation (FClock/(200 Hz × 255) − 1) and enforced by Timer_TMR ISR. Altering it breaks Immersion TouchSense 2000 effect timing compliance and may cause perceptual artifacts or failure to reproduce certified effects like Strong Click or Sharp Click.
