For engineers reviewing the LH7A404N0F000B3,55 datasheet, LH7A404N0F000B3,55 pinout, LH7A404N0F000B3,55 application, or LH7A404N0F000B3,55 equivalent, key selection criteria include ARM922T core compatibility, LFBGA-324 package footprint, 1.8 V core / 3.3 V I/O voltage domain separation, LCD timing control register mapping, and boot mode configuration via WIDTH0/WIDTH1/MEDCHG/INTBOOT pins.
Technical Context
The LH7A404N0F000B3,55 implements an ARM922T RISC core with MMU support for Windows CE™, 8 kB instruction + 8 kB data cache, and programmable PLL for core/bus clock derivation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ARM9-based SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT91SAM9260 | ARM926EJ-S core, 200 MHz, 64 kB SRAM, no integrated LCD controller, separate external LCD interface | Requires external LCD timing generator and level shifters for TFT panels; lacks native touch screen ADC channels | Select when LCD functionality is handled externally or when Linux kernel compatibility with AT91 bootstrap is prioritized over integrated graphics |
| EP9315 | ARM920T core, 200 MHz, 64 kB SRAM, integrated LCD controller (max 800×600), 4-channel 10-bit ADC, no USB host | Supports smaller displays and fewer touch points; lacks USB host capability for peripheral expansion | Select for cost-sensitive designs where USB host is unnecessary and display resolution ≤800×600 suffices |

FAQ
What is the maximum display resolution supported by the LH7A404N0F000B3,55 LCD controller?
The LH7A404N0F000B3,55 LCD controller supports up to 1024×768 resolution for TFT, STN, AD-TFT, and HR-TFT panels. This capability is enabled by its Advanced LCD Interface (ALI) with programmable timing registers and dedicated pixel clock (LCDDCLK), frame pulse (LCDFP), and line pulse (LCDLP) outputs. The controller also supports 64K-color output and multiple panel types without external timing logic.
Does the LH7A404N0F000B3,55 include hardware support for resistive touch screen controllers?
Yes, the LH7A404N0F000B3,55 integrates a dedicated 9-channel 10-bit ADC with five pins (AN0–AN4) assigned to X+, X−, Y+, Y−, and WIPER inputs - enabling direct connection and hardware-accelerated coordinate acquisition for 4-wire and 5-wire resistive touch screens. No external touch controller IC is required for basic touch functionality.
What boot options are available for the LH7A404N0F000B3,55, and how are they configured?
The LH7A404N0F000B3,55 supports boot from external ROM, NAND Flash, serial EEPROM, or XMODEM via its on-board boot ROM. Configuration is determined at power-on by latching WIDTH0/WIDTH1 (boot width), MEDCHG (media change), and INTBOOT (internal ROM enable) pin states. For example, INTBOOT = HIGH maps the lower 64 kB address space to internal boot ROM.
What are the power supply requirements for the LH7A404N0F000B3,55 core and I/O domains?
The LH7A404N0F000B3,55 requires separate 1.8 V for the core (VDDC/VSSC) and 3.3 V for I/O (VDD/VSS), with analog domains (VDDA/VSSA for PLLs; VDDAD/VSSAD for ADC) isolated for noise immunity. The oscillator pins XTALIN/XTALOUT operate at 1.8 V ±10%, and digital inputs are 5 V tolerant except for oscillator and analog pins.
How many USB interfaces does the LH7A404N0F000B3,55 support, and what modes are available?
The LH7A404N0F000B3,55 supports two full-speed USB 2.0 interfaces: one USB 2.0 Full Speed Host with two downstream ports (USBHDP0/USBHDN0 and USBHDP1/USBHDN1), and one USB 2.0 Full Speed Device (USBDP/USBDN). Both share a single PHY and require proper external termination and VBUS sensing circuitry per mode.
