Product details
Overview
LH7A404N0F092B3,55 from NXP Semiconductors is a 32-bit ARM9TDMI™ SoC with 266 MHz core clock, 133 MHz external bus interface, 80 kB on-chip SRAM, integrated LCD controller supporting up to 1024×768 resolution, and 9-channel 10-bit A/D converter with touch screen interface - deployed in handheld multimedia terminals requiring real-time graphics, battery-aware operation, and peripheral integration.
For engineers reviewing the LH7A404N0F092B3,55 datasheet, LH7A404N0F092B3,55 pinout, LH7A404N0F092B3,55 application, or LH7A404N0F092B3,55 equivalent, key selection considerations include ARM9TDMI core frequency (266 MHz), LFBGA-324 package compatibility, LCD controller timing support for AD-TFT/HR-TFT panels, USB 2.0 host/device dual-role capability, and boot mode configuration via WIDTH0/WIDTH1/MEDCHG/INTBOOT pins.
Technical Context
The LH7A404N0F092B3,55 implements an ARM922T core with MMU and 16 kB split I/D cache, enabling Windows CE™ execution. Its memory subsystem includes asynchronous and synchronous external bus interfaces supporting NAND Flash, PC Card, CompactFlash, and SDRAM - with configurable chip selects (nCS0–nCS7), byte lane enables (nBLE0–nBLE3), and clock enables (SCKE0–SCKE3).
Peripherals are organized across AHB and APB buses: the LCD controller uses ALI interface with dedicated signals (LCDVD0–LCDVD17, LCDDCLK, LCDFP, LCDLP); USB operates in full-speed host (two ports) and device modes with integrated PHY control (USBDCP, USBDP/USBDN, USBHDP0/USBHDN0); and the 10-bit ADC integrates touch screen X+/X−/Y+/Y− and wiper inputs (AN0–AN9) with dedicated analog power domains (VDDAD/VSSAD).

FAQ
What is the maximum supported LCD resolution for the LH7A404N0F092B3,55?
The LH7A404N0F092B3,55 supports up to 1024×768 resolution via its programmable LCD controller (ALI interface). This applies to STN, Color STN, AD-TFT, HR-TFT, and TFT panels - confirmed in the official NXP product data sheet section "Programmable LCD Controller" and Table 4 (LCD Controller Pins). The ALI interface provides dedicated timing signals (LCDDCLK, LCDFP, LCDLP) and data lanes (LCDVD0–LCDVD17) required for this resolution.
Does the LH7A404N0F092B3,55 support USB host and device modes simultaneously?
Yes, the LH7A404N0F092B3,55 supports concurrent USB 2.0 Full Speed host and device operation. It integrates two independent USB host ports (USBHDP0/USBHDN0 and USBHDP1/USBHDN1) and one USB device port (USBDP/USBDN) with USBDCP pull-up control. This dual-role capability is explicitly documented in the "Features" section of the NXP data sheet and enables use cases such as connecting peripherals while acting as a USB device to a PC for firmware updates.
What boot devices are supported by the LH7A404N0F092B3,55 internal Boot ROM?
The LH7A404N0F092B3,55 internal Boot ROM supports external ROM, NAND Flash, Serial EEPROM, and XMODEM protocols - as stated in the "Features" list of the NXP data sheet. Boot device selection is determined at power-on by latching WIDTH0/WIDTH1, MEDCHG, and INTBOOT pin states, enabling flexible field-programmable startup from multiple non-volatile media without external boot loader hardware.
How does the LH7A404N0F092B3,55 handle touch screen interface?
The LH7A404N0F092B3,55 integrates a dedicated 9-channel 10-bit A/D converter with specific pins assigned to touch screen functions: AN0/AN1 (X+ and X−), AN2/AN3 (Y+ and Y−), and AN4 (wiper input for 5-wire operation). This eliminates the need for an external touch controller, as confirmed in the "Features" section and Table 2 (Functional Pin List) of the NXP data sheet. Analog power domains (VDDAD/VSSAD) ensure noise immunity during digitization.
What is the operating voltage range for the LH7A404N0F092B3,55 core and I/O?
The LH7A404N0F092B3,55 operates at 1.8 V core voltage (for 200 MHz) or 2.1 V core voltage (for 266 MHz), with 3.3 V I/O voltage - except XTALIN, which is strictly 1.8 V ±10%. Five-volt tolerant digital inputs are supported on most I/O pins (excluding oscillator pins), as specified in the "Operating Voltage" section of the NXP data sheet and verified in Table 2 pin descriptions.
