ATMXT336S-MAUR - 336-Node Touchscreen Controller IC | Microchip
MPN: ATMXT336S-MAUR ✓ فعالATMXT336S-MAUR جائزہ
A capacitive touchscreen controller is a mixed-signal IC that drives and senses a grid of mutual-capacitance nodes on a touch panel, converts raw capacitance changes into digitized touch coordinates, and reports gesture data to a host processor. Within the power management and human-interface hierarchy, it sits between the passive touch panel and the application processor, forming part of the sensor and interface IC layer of a mobile system.
Key features include 336 mutual-capacitance sensing nodes, support for 2.0 mm passive stylus input, moisture robustness for wet-finger tracking, and superior electrical noise immunity for operation in hostile AC-charger and display-noise environments, according to the Microchip product page.
The maXTouch architecture uses patented capacitive touch acquisition technology with on-chip signal processing, enabling high signal-to-noise ratio touch reporting at high report rates. This makes the mXT336S well suited to dense sensor patterns on thin phone form factors where water rejection and stylus resolution are critical differentiators.
Typical applications include premium smartphone touchscreens, small-to-medium tablet and phablet panels, and portable consumer devices requiring passive stylus support and wet-hand operation.
When designing with the mXT336S, confirm panel node count and pin mapping against the maXTouch family configuration, and note that Microchip officially recommends the ATMXT336U as the alternative touch controller for this part.

Premium Smartphone Touchscreens
The ATMXT336S-MAUR is purpose-built for high-performance smartphones, using Microchip's patented capacitive touch technology to deliver 336 mutual-capacitance nodes for dense, fine-pitch sensor patterns on thin phone stacks. Its 2.0 mm passive stylus support enables pen-like drawing accuracy without an active stylus, while moisture robustness keeps tracking reliable with wet fingers, a common real-world failure mode for lesser controllers. Superior electrical noise immunity maintains touch accuracy against charger and display noise in slim, antenna-dense phones. Implemented as the controller between the ITO sensor and the application processor over the host interface, it reports filtered touch and gesture data at high report rates. The trade-off is that a 336-node controller consumes more processing and panel-design effort than lower-count variants, but it is the cost of premium touch UX.

Tablet and Phablet Panels
Mid-size tablet and phablet panels need high node counts to preserve linearity across larger active areas, and the mXT336S's 336 sensing nodes provide the density required for accurate multi-touch and passive stylus input on screens up to the 7-inch class that Microchip cites for this family. Moisture robustness matters in tablets used in kitchens, education, and field service where wet or damp hands are routine, and the mXT336S's wet-finger tracking directly addresses that scenario. Its noise immunity is equally important because tablets integrate bright displays and fast chargers that couple noise into the touch sensor. In the signal chain, the controller drives the sensor grid, acquires mutual capacitance, and streams digitized touches to the SoC. Designers should budget for panel-profile tuning to match the specific ITO pattern and stack-up.

Passive Stylus Note-Taking Devices
Digital note-taking products that use inexpensive passive (capacitive) styli rather than active pens benefit directly from the mXT336S's 2.0 mm passive stylus support, which resolves the fine tip geometry that generic controllers smear into large blobs. The 336-node grid supplies the spatial sampling needed for legible handwriting, while on-chip acquisition processing maintains a stable signal-to-noise ratio so stroke jitter stays low during fast writing. Moisture robustness prevents hand-contact artifacts around the writing palm, and noise immunity keeps the input stable while the device charges over a USB charger, exactly when note-taking sessions typically occur. As with any passive-stylus design, linearity across the display edge should be validated during panel tuning; the controller's stylus performance depends on sensor geometry as well as firmware configuration.

Wet-Environment Consumer Devices
Devices used outdoors or in humid environments, such as ruggedized phones, marine handhelds, and outdoor kiosks, must keep touch functionality intact with rain, condensation, or wet gloves-and-fingers conditions. The mXT336S is explicitly specified for moisture robustness, meaning its acquisition algorithm rejects water-film capacitance that causes ghost touches on standard controllers. Combined with superior electrical noise immunity, it remains reliable when the device is also connected to a noisy charger or sits near high-brightness LED backlight drivers. In the system, the controller sits between the shielded or unshielded sensor stack and the host MCU, filtering raw capacitance frames and reporting only valid touches. Designers should pair it with panel materials tested for water rejection; the controller handles the signal side but the cover-lens and sensor design determine the wet-touch ceiling.

Automotive Touchscreens (via mXT336S-A)
For infotainment and climate-control touchscreens, the automotive-qualified mXT336S-A extends this family into vehicles, optimized for 7-inch displays and enabling single-layer shieldless sensor designs that reduce cost and stack thickness. While the consumer ATMXT336S-MAUR itself is not the AEC-qualified part, its architecture is the same maXTouch platform, so panel profiles and tuning experience port directly when moving to the -A variant. Automotive cabins impose severe noise conditions, including inverters, RF transceivers, and fast chargers, which the maXTouch noise-immunity architecture is designed to tolerate. In a vehicle HMI, the controller reports touch and hover data to the head-unit SoC over the host interface and must maintain accuracy under glove, wet, and multi-touch use. Programs requiring formal qualification documentation should order the -A suffix part rather than the consumer MAUR.

High-Volume Consumer Electronics Manufacturing
For contract manufacturers building millions of touch devices per year, the ATMXT336S-MAUR ships on tape and reel, the -R packaging suffix, for automated pick-and-place lines, and is lead free and RoHS compliant to meet global environmental regulations. Verified channel data shows 20000-piece stock positions and volume pricing near $2.83 per unit at 20000+ quantity as of 2026-09-19, supporting aggressive BOM targets in cost-driven consumer hardware. The tray-packed ATMXT336S-MAUD variant serves engineering builds and low-speed lines without changing the PCB footprint, since the silicon and package are identical. For supply-chain resilience, Microchip officially designates the ATMXT336U as the alternative touch controller, giving procurement a sanctioned second source within the maXTouch roadmap. Buyers should confirm date codes and reel quantities with distributors before releasing large production orders.

ڈیزائن نوٹس
Do not confuse the ordering suffixes when purchasing: -MAUR is tape and reel for automated assembly, while -MAUD is tray packing of the identical die. They are electrically interchangeable on the same PCB, but mixing reel and tray quantities disrupts SMT line planning. Additionally, Microchip explicitly designates ATMXT336U as the recommended alternative for the mXT336S; treat any other family member (336T, 336S-A) as requiring panel-profile revalidation, because node mapping and firmware configuration differ even within the same node count.
The mXT336S is specified for superior electrical noise immunity and moisture robustness, but its real-world performance depends on the sensor stack. Route touch sense lines away from switching regulators, backlight LED drivers, and RF antenna feeds, and follow Microchip's maXTouch panel layout guidance for guard and shield placement. For wet-finger applications, validate the moisture algorithm against your cover-lens material and ITO geometry during panel tuning; the controller's wet-touch rejection is only as good as the sensor design it drives.
Place the mXT336S controller close to the touch sensor flex-tail connector to keep sense-line loop area small and reduce coupled noise from the display and charger. Use solid ground plane under the controller but keep copper off the flex routing region per Microchip panel guidelines. Decouple the supply per the manufacturer datasheet recommendations with local ceramic capacitors at the supply pins. For 2.0 mm passive stylus accuracy, the sensor pattern linearity near display edges matters as much as controller resolution, so review the panel design together with the controller placement.
