Product details
Overview
CY8C20466A-24LQXI from Cypress Semiconductor is a PSoC® 1 mixed-signal array IC configured with the TS2000 Haptics User Module for tactile feedback generation. It integrates two 16-bit timers (Timer0 and Timer2) to generate a ~23 kHz PWM output and precise 5-ms haptic effect update intervals, operates at up to 3.3 V, and supports up to 14 Immersion TouchSense 2000 haptic effects in embedded capacitive touch interfaces.
For engineers reviewing the CY8C20466A-24LQXI datasheet, CY8C20466A-24LQXI pinout, CY8C20466A-24LQXI application, or CY8C20466A-24LQXI equivalent, key selection criteria include PWM timing resource allocation, actuator drive signal routing (PWM_Port/PWM_Pin and AmplifierEnable_Port/AmplifierEnable_Pin), supported effect count (14), flash usage range (15,922 bytes), and RAM footprint (43–1803 bytes depending on enabled effects).
Technical Context
The CY8C20466A-24LQXI implements haptic feedback using firmware-driven timer resources: Timer_PWM generates ~23 kHz PWM (90-cycle ISR duration), while Timer_TMR provides 5-ms effect update intervals. Both timers operate from the IMO clock (recommended 24 MHz), and the module supports Interrupt and Polled update methods.
It requires external actuator drive circuitry (e.g., TPA6205A amplifier) and supports two validated actuators: Sanyo NRS-2574i (≤150 g devices) and Jinlong Z6DL2A017000B (>150 g). The TS2000 firmware layer abstracts effect playback via TS2000_1_PlayEffect(), enabling concurrent CPU execution during effect playback.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PWM Frequency | ~23 kHz - ensures inaudible actuation and avoids mechanical resonance in common ERM actuators |
| Effect Update Interval | 5 ms ±10% - synchronizes haptic waveform sequencing to Immersion TouchSense 2000 library timing requirements |
| Flash Usage | 15,922 bytes - worst-case footprint for full 14-effect configuration with compiler-dependent overhead |
| RAM Usage | 43–1803 bytes - scales directly with number and type of enabled haptic effects |
| Supply Voltage | 3.3 V ±5% - matches standard actuator driver (TPA6205A) and CapSense system rail |
| Timer Resources | Timer0 + Timer2 - dedicated 16-bit timers; no digital block consumption, freeing PSoC resources for CapSense or other functions |
Pinout & Package
LQFP-24 package (7 × 7 mm, 0.4 mm pitch) with 16 general-purpose I/O pins, including dedicated routing paths for PWM output and amplifier enable signals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0[0]–P0[7] | GPIO / CapSense input | Supports up to 8 capacitive sensing buttons; configurable as analog or digital inputs |
| P1[0], P1[1] | I²C SDA/SCL | Reserved for I²C interface; not recommended for TS2000 PWM or SHDN# routing |
| P1[2]–P1[7] | GPIO / PWM output / SHDN# | Configurable for PWM_Port/PWM_Pin (e.g., P1[4]) and AmplifierEnable_Port/AmplifierEnable_Pin (e.g., P1[5]) |
| VDD, VSS | Power supply | 3.3 V core and I/O supply; decoupling required per PSoC 1 design guidelines |
Key Features
| Feature | Design Value |
|---|---|
| 14 Immersion TouchSense 2000 effects | Enables standardized, perceptually tuned haptic responses (e.g., Strong Click, Sharp Click 60%) without custom waveform development |
| Firmware-based dual-timer architecture | Eliminates need for dedicated digital blocks-preserves PSoC 1 resources for concurrent CapSense and system control tasks |
| Non-blocking effect playback | Allows full CPU operation during haptic playback; no firmware stall or polling loop required |
| Actuator-optimized PWM timing | 23 kHz carrier frequency avoids audible noise and aligns with ERM mechanical response limits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar haptics controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C20336H-24LQXI | Same PSoC 1 platform but uses one digital block + software timer; higher CPU load (~12% vs. <2% during playback) | Limited to 8 haptic effects; lower flash usage (14,652 bytes); no dual-timer hardware offload | Select when CPU headroom exists and fewer effects suffice |
| CY8C22345H-24LQXI | Two-digital-block configuration enables full hardware PWM + hardware 5-ms timer; zero CPU load during playback | Supports same 14 effects but consumes two digital blocks; incompatible pinout and memory map | Select for ultra-low-latency, deterministic haptics in resource-rich designs |
Compared with CY8C20336H-24LQXI, this part reduces CPU loading during haptic playback from ~12% to near-zero baseline; compared with CY8C22345H-24LQXI, it trades digital block usage for timer resource efficiency-ideal for CapSense + haptics coexistence in space-constrained LQFP-24 layouts.

FAQ
What actuator drivers are compatible with CY8C20466A-24LQXI?
The device is characterized and validated with the TPA6205A amplifier operating from a 3.3 V supply. It drives two specified actuators: Sanyo NRS-2574i (for devices ≤150 g) and Jinlong Z6DL2A017000B (for heavier units). External drive circuit design must match the 23 kHz PWM frequency and 3.3 V logic levels.
How does CPU loading behave during haptic playback?
During playback, only two short ISRs execute: Timer_PWM (~90 cycles at 24 MHz) and Timer_TMR (5 ms interval). CPU remains fully available for other tasks. When no effect is playing, TS2000 imposes zero CPU load-no background polling or timer overhead is incurred.
Can I change haptic effects dynamically at runtime?
Yes. Effects are selected at compile time via the TS2000 configuration wizard, but the TS2000_1_PlayEffect() API accepts a pointer to effect data, allowing runtime selection among enabled effects. Disabled effects are excluded from flash and cannot be invoked.
Is the CY8C20466A-24LQXI RoHS compliant and halogen-free?
Yes. Per Cypress document #001-64564 Rev. *D and Infineon's product compliance database, CY8C20466A-24LQXI meets RoHS Directive 2011/65/EU and JEDEC JS709B halogen-free requirements. Lead finish is matte tin, and packaging conforms to IPC/JEDEC J-STD-020 moisture sensitivity level 3.
