Product details
Overview
LH75411N0Q100C0 from NXP Semiconductors is a 144-pin LQFP ARM7TDMI-S™ System-on-Chip microcontroller operating at up to 84 MHz, featuring 32 kB on-chip SRAM (16 kB TCM + 16 kB internal), an 8-channel 10-bit ADC, integrated touch screen controller, real-time clock, three capture/compare/pwm timers with watchdog, and a full-color LCD controller supporting VGA–XGA resolutions across STN/TFT/HR-TFT/AD-TFT panels - deployed in industrial HMI and portable medical display systems.
For engineers reviewing the LH75411N0Q100C0 datasheet, LH75411N0Q100C0 pinout, LH75411N0Q100C0 application, or LH75411N0Q100C0 equivalent, this page delivers verified functional identity, validated package mapping, confirmed peripheral register-level behavior, and precise alternative-part selection guidance for embedded SoC integration.
Technical Context
The LH75411N0Q100C0 implements an ARM7TDMI-S™ core with tightly coupled memory architecture, enabling deterministic interrupt latency and efficient real-time control. Its AHB/APB bus matrix supports concurrent access to SRAM, peripherals, and external memory interfaces without arbitration stalls.
It integrates a dedicated Advanced LCD Interface driving 12-bit video data buses with programmable timing for STN, TFT, HR-TFT, and AD-TFT panels, plus a synchronous serial port compatible with SPI, Microwire, and SSI protocols - all managed via configurable I/O pull-up/down and drive strength per pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM7TDMI-S™ - 32-bit RISC processor with Thumb instruction set, JTAG debug support, and vectored interrupt controller for sub-10 µs response. |

| UARTRX0/UARTRX1/UARTRX2 UARTTX0/UARTTX1/UARTTX2 |
Asynchronous Serial Interfaces | Three independent UARTs - U0 supports CAN-capable pins on LH75401 only; U1 and U2 provide high-speed host/device communication up to 3.2 Mbps (U2 @ 70 MHz system clock). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Touch Screen Controller | Hardware-accelerated 4-wire resistive touch digitization using AN0–AN3, eliminating need for external touch controller IC and reducing BOM count. |
| Low-Power Modes (Standby/Sleep/Stop) | Core clock gating and peripheral power-down reduce active current to <1 mA in Sleep mode while retaining SRAM content and RTC operation. |
| 5 V Tolerant Digital I/O | All GPIO pins withstand 5 V logic levels - simplifies interface to legacy peripherals and level-shifting circuitry in mixed-voltage systems. |
| JTAG Boundary Scan & Debug | Full IEEE 1149.1-compliant test access port with RTCK for adaptive clocking - enables production testing and in-circuit debugging without requiring SWD or proprietary probes. |
| Single 3.3 V Supply Operation | Eliminates need for multiple voltage rails; internal linear regulator generates core voltage (VDDC) from VDD, reducing external component count and board area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM7-based SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LH75401N0Q100C0 | Identical pinout and memory/peripheral architecture, but includes CAN 2.0B controller; otherwise functionally identical to LH75411N0Q100C0. | Required where CAN bus communication with motor drives or automotive ECUs is needed; unnecessary overhead if CAN is unused. | Select LH75401N0Q100C0 only when CAN protocol support is mandatory; otherwise LH75411N0Q100C0 reduces software validation scope and eliminates unused peripheral drivers. |
| AT91SAM7S256 | ARM7TDMI-based MCU with 256 kB Flash, 64 kB SRAM, no integrated LCD controller, and no touch screen interface; uses external parallel bus for display. | Suitable for non-display-centric applications or where external graphics controller is preferred; lacks native touch digitization capability. | Choose AT91SAM7S256 when Flash storage and larger RAM are prioritized over integrated display/touch functionality; requires additional components for LCD and touch support. |
Compared with LH75401N0Q100C0, the LH75411N0Q100C0 removes CAN hardware to reduce cost and simplify certification, while retaining identical LCD, ADC, and UART capabilities; versus AT91SAM7S256, it trades Flash density for integrated display/touch acceleration and lower BOM count in HMI-focused designs.

FAQ
What is the maximum operating frequency of the LH75411N0Q100C0?
The LH75411N0Q100C0 operates at a maximum CPU frequency of 84 MHz, achieved using its internal PLL locked to a 14–20 MHz crystal input. This speed is sustained across the full −40°C to +85°C temperature range and supports real-time execution of graphics rendering, touch processing, and serial communication stacks without throttling.
Does the LH75411N0Q100C0 include a built-in CAN controller?
No, the LH75411N0Q100C0 does not include a CAN controller. It is explicitly defined in the product documentation as the variant of the LH754xx family that omits CAN 2.0B functionality - unlike the LH75401N0Q100C0, which integrates a full CAN 2.0B controller. All other peripherals remain identical between the two parts.
How many UART interfaces does the LH75411N0Q100C0 support?
The LH75411N0Q100C0 supports three independent UART interfaces: UART0 (pins PE2/PE3), UART1 (pins PD4/PD3), and UART2 (pins PE0/PE1). UART0 and UART1 support baud rates up to 921.6 kbps with a 14.756 MHz crystal; UART2 supports up to 3.2256 Mbps when the system clock runs at 70 MHz.
What LCD panel types are supported by the LH75411N0Q100C0's integrated controller?
The LH75411N0Q100C0's Color LCD Controller supports STN, TFT, HR-TFT, and AD-TFT display technologies. It delivers 12-bit color depth (4,096 colors) at VGA resolution, 8-bit palettized color at SVGA, and 4-bit grayscale/color at XGA - with programmable timing, polarity reversal, and power-save signals for each type.
Is the LH75411N0Q100C0 pin-compatible with the LH75401N0Q100C0?
Yes, the LH75411N0Q100C0 is fully pin-compatible with the LH75401N0Q100C0 in the 144-pin LQFP package. Both share identical pin assignments, electrical characteristics, and memory/peripheral mappings - differing only in the absence of CAN TX/RX pins (PE3/PE2) on the LH75411N0Q100C0, which are repurposed as UART0 signals.
