XMC4108-Q48K64AB - 80MHz Cortex-M4 64KB MCU | Infineon
MPN: XMC4108-Q48K64AB ✓ Hoạt độngXMC4108-Q48K64AB Tóm tắt
A microcontroller is a programmable integrated circuit that combines a processor core, memory, and peripherals within one semiconductor device. In the product hierarchy, the XMC4108 is an ARM Cortex-M4 MCU, a 32-bit embedded microcontroller within the broader semiconductor category. Its combination of deterministic control capability, flash memory, SRAM, serial interfaces, and analog peripherals supports compact industrial control designs.
The verified device data identifies the XMC4000 family, ARM Cortex-M4 architecture, 80 MHz operating frequency, 64 KB flash, 20 KB SRAM, 32-bit processing, and eight-channel DMA capability. Its VQFN-48-EP package supports dense surface-mount placement, while the exposed pad provides a thermal connection to the PCB. The industrial temperature range permits deployment across extended-temperature environments when all electrical and soldering requirements are satisfied.
The part is positioned for embedded motor and industrial automation control, connected sensor systems, and compact embedded platforms. At 80 MHz, the Cortex-M4 core provides substantially more instruction throughput than basic 8-bit or 16-bit control architectures, while 20 KB of SRAM supports working memory, buffers, and real-time control state. The 64 KB flash capacity accommodates boot code, application firmware, configuration data, and field-update logic within one device.
The listed 3.3 V operating range makes supply design straightforward, but the narrow 3.13 V to 3.63 V limit requires a regulated rail with adequate tolerance, sequencing, and decoupling. Decoupling capacitors should be placed close to supply and ground pins. Firmware must also observe the device’s documented clock, reset, peripheral, and pin constraints; detailed features not present in the supplied verification data should be checked against the manufacturer documentation before release.

Ứng dụng tiêu biểu
XMC4108-Q48K64AB phù hợp cho 7 Áp dụngs: Industrial Embedded Control, Motor Control and Automation, Connected Sensor Node, Data Acquisition Front End, Communication Controller, HMI and Panel Control, Robotics and Embedded Modules.
Industrial Embedded Control
The XMC4108-Q48K64AB fits compact industrial controllers that require an 80 MHz ARM Cortex-M4 core, 64 KB flash, and 20 KB SRAM within a 7 mm by 7 mm VQFN-48-EP package. Its stated -40°C to +125°C range supports extended-temperature designs when the complete product specification is met. The MCU can execute control loops and host communications firmware while eight DMA channels offload transfers between SRAM and peripherals. A regulated rail must stay within the verified 3.13 V to 3.63 V range. Because exact timer and I/O assignments were not supplied, designers should verify pin multiplexing and peripheral availability against the manufacturer documentation before finalizing the PCB.
Được đề xuất
Motor Control and Automation
An 80 MHz Cortex-M4 core gives the XMC4108-Q48K64DB useful control-loop throughput for motor-control, actuator, and automation subsystems. Eight DMA channels can move sampled or control data with reduced processor intervention, while the listed 12-bit, 12-channel ADC supports analog feedback acquisition. The 20 KB SRAM provides working space for control variables and communication buffers. Exact PWM outputs, capture blocks, encoder interfaces, and pin assignments remain unverified in the supplied snippets, so motor-control suitability requires a documented peripheral and timing review. Power regulation must preserve the verified 3.13 V to 3.63 V range under switching and transient load conditions.
Được đề xuất
Connected Sensor Node
The XMC4108-Q48K64AB can serve as the local controller in a connected sensor node that samples analog inputs, filters data, and forwards results through an industrial communications interface. Its 12-bit ADC is listed alongside a 20 KB SRAM, allowing firmware to maintain measurement buffers and protocol state, while eight DMA channels can support efficient peripheral data movement. The 64 KB flash capacity is suitable for constrained embedded firmware rather than large graphical applications. Before schematic release, verify the required serial peripherals, package pins, clock sources, and low-power modes in the official documentation because those details were not supplied in the verified snippets.
Được đề xuất
Data Acquisition Front End
For compact data-acquisition equipment, the XMC4108-Q48K64AB combines a 32-bit Cortex-M4 processor with a listed 12-bit, 12-channel ADC, enabling sampled measurements to be processed locally. The 80 MHz operating frequency supports time-sensitive filtering, calibration, and data formatting, and eight DMA channels can reduce CPU overhead during transfers. Its 20 KB SRAM is appropriate for bounded acquisition buffers, while 64 KB flash holds firmware and configuration. Sampling rate, ADC trigger architecture, input range, acquisition time, and channel multiplexing were not included in the verified data, so signal-chain design must wait for confirmation from the manufacturer datasheet.
Được đề xuất
Communication Controller
The XMC4108-Q48K64AB is suitable for protocol gateways and embedded communications controllers that need deterministic 32-bit processing alongside eight DMA channels. The Cortex-M4 core at 80 MHz can manage message processing, state machines, and serial traffic, while 64 KB flash and 20 KB SRAM provide a compact firmware platform. Network or bus transceivers remain external because the verified snippets do not identify the MCU’s complete communications peripheral set. Designers should compare pin multiplexing, baud-rate support, DMA routing, and protocol firmware dependencies against the exact datasheet, and should validate timing under the maximum specified traffic load.
Được đề xuất
HMI and Panel Control
The XMC4108-Q48K64AB can manage compact human-machine interface and control-panel logic where an 80 MHz MCU handles input events, state management, and communications. Its 64 KB flash and 20 KB SRAM suit moderate embedded workloads, and the small 7 mm by 7 mm VQFN-48-EP package helps reduce board area. No LCD controller, graphics interface, touch-controller resource, or exact digital I/O count was present in the supplied evidence. Those capabilities must be checked before assigning a display or touch interface. Power sequencing, low-noise routing around analog inputs, and exposed-pad layout should be validated during prototype bring-up.
Được đề xuất
Robotics and Embedded Modules
For robotics controllers and compact embedded modules, the XMC4108-Q48K64AB offers an 80 MHz ARM Cortex-M4 core, eight DMA channels, and local memory in a surface-mount package. The processor can coordinate sensor acquisition, actuator commands, and communications while the 3.3 V-class supply range supports integration into embedded modules. Exact timer channels, encoder interfaces, USB support, and package-level I/O were not included in the verified data, so robotics assignments require a complete pin and peripheral review. Keep sensitive analog traces short, provide local supply decoupling, and test firmware timing on hardware rather than relying on nominal core frequency alone.

Ghi chú thiết kế
The verified operating range is 3.13 V to 3.63 V, so use a regulated 3.3 V-class supply with control over startup, load transients, and ripple. Place bypass capacitors directly beside the MCU supply and ground pins, and keep the return path short. Because individual rail-current and absolute-maximum limits were not supplied, confirm them in the manufacturer datasheet rather than estimating them from the CPU frequency.
Treat the VQFN exposed pad as both a package feature and a potential thermal path. Use the manufacturer land pattern, create a solderable thermal region, and minimize disruption of copper beneath the device. Actual heating depends on supply voltage, processor activity, I/O loading, ambient temperature, and board construction, none of which is fully specified in the verified snippets; perform thermal testing instead of assuming the 7 mm by 7 mm package alone guarantees adequate cooling.
Use the official VQFN-48-EP land pattern and pin table, verify pin 1 orientation, and provide all documented exposed-pad connections. Keep decoupling at the associated pins, route clock and reset away from noisy switching nodes, and reserve clean ground around any analog inputs used with the 12-bit ADC. Assembly inspection should include exposed-pad voiding because hidden solder issues can impair both electrical and thermal performance.
Do not treat the related ordering code XMC4108Q48K64ABXUMA1, the related XMC4108-Q48K64-BA result, or the XMC4108-F64K64-BA as a drop-in substitute without checking the official ordering table. A valid replacement must match the land pattern and pin functions and must preserve memory, voltage, clock, peripheral, toolchain, and qualification requirements. Validate reset behavior, clock startup, ADC scaling, DMA routing, and firmware timing on prototypes.
Thông tin tuân thủ
