Product Overview
The LH79520N0Q000B1 is a highly integrated 32-bit microcontroller built on the powerful ARM7TDMI-S processor core with ARM720T architecture, originally developed by Sharp and supported within the NXP semiconductor ecosystem. Operating at frequencies up to 77.4 MHz, this system-on-chip solution features an internal Memory Management Unit (MMU), an 8KB data/instruction cache, and 32KB of on-chip SRAM. Specifically designed for feature-rich embedded applications that require a sophisticated user interface, the integrates a versatile direct-drive LCD controller that supports both monochrome and high-color STN/TFT panels. With its low power consumption architecture and extensive integrated peripherals, this microcontroller provides an efficient and cost-effective engine for hand-held terminals, industrial controllers, and smart consumer appliances.
Core Advantages
Integrated High-Performance LCD Controller
The onboard programmable LCD controller supports up to 800×600 resolution and up to 65536 colors (16bpp) on TFT panels. This eliminates the need for expensive external display drivers and dedicated video memory, significantly reducing overall system complexity and costs.
Advanced Memory Management (MMU)
Featuring a hardware Memory Management Unit (MMU) combined with an 8KB cache, the LH79520N0Q000B1 can seamlessly run robust platform operating systems such as Linux and Windows embedded extensions, ensuring secure memory partitioning and high application software processing speeds.
Comprehensive Peripheral Integration
Equipped with a diverse array of communication interfaces including 3 UARTs, Synchronous Serial Ports (SSP), I²C, IrDA, External Memory Interface (EMI), and multiple DMA channels, the IC simplifies interfacing with sensors, external Flash/SDRAM storage arrays, and network modems.
Excellent Thermal and Energy Efficiency
Designed with flexible power management control blocks, including dynamic clock scaling and software-selectable Standby and Suspend states. This low-power configuration minimizes thermal dissipation and helps maximize operating runtime in battery-driven devices.

Frequently Asked Questions
Q1: Is the LH79520N0Q000B1 microcontroller original factory stock?
A: Yes, we provide 100% genuine, brand-new LH79520N0Q000B1 processors sourced through verified manufacturer channels with full date code traceability.
Q2: Can this chip run standard embedded operating systems like Linux?
A: Yes, because the ARM720T architecture inside the LH79520 contains a complete hardware Memory Management Unit (MMU), it is fully capable of hosting embedded Linux distributions and RTOS platforms requiring virtual memory mappings.
Q3: Does the internal LCD controller require external video RAM (VRAM)?
A: No, the integrated LCD controller can use a portion of the main system memory (such as external SDRAM connected via the External Memory Interface) as frame buffers, removing the necessity of standalone VRAM chip configurations.
Q4: How can I request the full technical reference manual and BGA/LQFP footprint layout specifications?
A: Please complete our website’s Quick Inquiry form detailing your engineering project requirements, and our hardware application engineers will send the requested document package to you within 24 hours.
