ATMXT1386-Z2UIR 개요
A capacitive touch controller is an interface IC that measures changes in capacitance across a touch sensor grid, converts those measurements into touch coordinates, and communicates them to a host processor. Within the semiconductor hierarchy it sits under data acquisition ICs, specifically touch screen converters and controllers, and forms part of the broader human-machine interface (HMI) signal chain that includes the sensor glass, the controller IC, and the host firmware.
Key differentiating features include the 1386-node acquisition capacity, which supports large-format touch panels with many simultaneous sensing channels; the multi-chip architecture that lets four devices cooperate on a single panel; and the integrated 32-bit AVR processing that performs filtering and gesture detection on-chip, reducing host CPU load. The maXTouch platform firmware can be updated in-system, enabling tuning for different glass stack-ups.
The charge-transfer acquisition technique offers strong signal-to-noise performance against display noise, which is important for designs where the touch sensor is integrated into or placed close to an LCD. On-chip AVR computation allows advanced touch features such as multi-touch tracking, palm rejection, and moisture compensation depending on the configured firmware.
Typical applications include industrial HMI touch panels, large-format touch screens for appliances and kiosks, medical equipment control surfaces, and embedded systems requiring robust multi-touch input on medium-to-large sensor arrays.
A key design consideration is that this device has been discontinued by Microchip; the manufacturer officially recommends the ATMXT1066T2 touch controller as the alternative for new designs, so availability should be confirmed before committing to a BOM.

Industrial HMI Touch Panels
Industrial human-machine interface panels demand touch controllers that survive electrically noisy environments, and the ATMXT1386-Z2UIR addresses this with charge-transfer acquisition technology that rejects display and switching-supply noise. Its 1386 sensing nodes support large-format control screens typical of factory automation consoles, while the on-chip 32-bit AVR core performs signal filtering and multi-touch tracking locally, reducing load on the host PLC or embedded controller. In this application the controller sits between the sensor glass and the host MCU over a serial interface, with firmware tuned to the specific glass stack-up and cover thickness. The multi-chip architecture allows four devices to cooperate across one large panel, a benefit for oversized operator stations. Given the device's EOL status, existing industrial programs typically use it for service replacements while new HMI designs migrate to the ATMXT1066T2.

Large-Format Appliance and Kiosk Touch Screens
Self-service kiosks and premium appliances use medium-to-large touch panels where many simultaneous sensor channels must be scanned quickly; the ATMXT1386-Z2UIR's 1386-node capacity and 4-chip multi-chip design were created for exactly this scale. The integrated 32-bit AVR processor handles gesture detection, multi-touch tracking, and moisture compensation on-chip, so the host system receives clean coordinate data rather than raw capacitance measurements. The charge-transfer technique resists the display noise typical of kiosk LCD stacks, protecting touch accuracy across the panel. Designers typically configure the maXTouch firmware object for the specific sensor pattern and cover-lens thickness, then calibrate during production. Because the ATMXT1386-Z2UIR is discontinued, kiosk service organizations use it for field spares of deployed units, while new kiosk platforms adopt Microchip's recommended ATMXT1066T2 active platform.

Medical Equipment Control Surfaces
Medical diagnostic and monitoring equipment relies on dependable touch input, and the ATMXT1386-Z2UIR's on-chip processing delivers stable, low-latency multi-touch response on medium-to-large control panels. Its charge-transfer acquisition architecture provides strong signal-to-noise performance against the noise generated by backlights and switching power stages common in medical displays, and the 1386-node capacity covers the large glass areas used on bedside monitors and diagnostic consoles. The multi-chip solution allows the sensor matrix to be driven by four coordinated devices, supporting oversized panels without a host redesign. Firmware-level filtering and palm-rejection features improve usability during clinical operation. As the part is now EOL, medical OEMs typically qualify the ATMXT1066T2 as the forward platform while maintaining ATMXT1386-Z2UIR stock for sustaining existing certified designs.

Embedded Systems Multi-touch Input
General embedded systems built around Atmel/Microchip AVR platforms frequently pair a maXTouch controller with an AVR or ARM host for HMI input, and the ATMXT1386-Z2UIR fits designs that need many touch channels without external acquisition circuitry. Its 32-bit AVR core offloads scanning, filtering, and coordinate computation from the host, communicating results over a standard serial host interface; the maXTouch firmware is configurable and updatable in-system for tuning to different glass thicknesses and layouts. The 4-chip architecture scales the 1386-node capacity across one sensor matrix, enabling multi-touch on panels too large for single-chip controllers of its era. For teams already sustaining AVR-based products, this controller preserves design continuity. New embedded projects should begin with the ATMXT1066T2, which Microchip recommends for the discontinued ATMXT1386 family.

Point-of-Sale and Interactive Display Terminals
Point-of-sale terminals and interactive displays need touch controllers that maintain accuracy under continuous public use, and the ATMXT1386-Z2UIR provides robust multi-touch with on-chip tracking, gesture recognition, and noise rejection from its charge-transfer architecture. The 1386-node sensing capacity suits wide or tall screens found in POS counters and interactive signage, and the multi-chip scheme lets four controllers scan one large matrix coherently. Its on-board 32-bit AVR processing reduces host interface traffic to finished coordinate and gesture data, simplifying firmware on the terminal processor. Display-noise immunity keeps touch performance stable when the sensor is laminated close to the LCD. Because this device is discontinued, new POS hardware adopts the ATMXT1066T2 recommended by Microchip, while legacy terminal service uses remaining ATMXT1386-Z2UIR broker stock.

Automotive-adjacent and Rugged Display Retrofit
Rugged display retrofits, including off-highway and specialty-vehicle consoles, have used maXTouch controllers such as the ATMXT1386-Z2UIR for their noise immunity and large sensor capacity. The charge-transfer acquisition method tolerates the electrical environment of vehicle power systems better than simpler capacitance-sensing schemes, and the 1386-node, 4-chip design covers the wide panels typical of instrument and control clusters. The integrated 32-bit AVR core executes filtering and palm rejection locally, important in vibrating, gloved-operation environments. Retrofit integrators value that the maXTouch firmware object can be retuned without changing hardware when a different glass is fitted. Note that the ATMXT1386-Z2UIR itself is a standard (not AEC-Q100) industrial-grade device and is discontinued; new rugged designs should evaluate Microchip's automotive-grade maXTouch offerings including the ATMXT1066T2 platform.

설계 노트
The ATMXT1386-Z2UIR is discontinued and Microchip officially recommends the ATMXT1066T2 as the alternative touch controller. Do not release new PCB designs around the LCC64 footprint of the ATMXT1386 without a last-time-buy plan, since remaining supply is broker stock with unguaranteed quality and lead time. When migrating, budget for PCB layout changes, maXTouch firmware recompilation, and re-tuning of the acquisition configuration to the target sensor glass.
As a 64-terminal HVQCCN (LCC64) leadless package in the QFN family, the device requires a defined land pattern per the maXTouch 1386 datasheet with adequate thermal via arrays under the exposed pad. Follow Microchip maXTouch hardware design application guidance for sensor trace routing: keep sensor lines away from switching regulators and backlight drivers, and maintain the recommended series resistors and ESD protection on connections exposed to the touch panel.
The charge-transfer acquisition architecture is designed to reject display noise, but performance depends on correct sensor harness routing and grounding. Keep the flex or PCB carrying sensor lines short and shielded per the maXTouch design guide, and avoid parallel routing with high-current or switching nodes. When the touch sensor is integrated close to the LCD, re-tune the noise-suppression configuration during system bring-up rather than reusing default firmware objects.
