Detailed Description

ARM9-based application processor for embedded systems. Integrates CPU, memory interfaces, display control, storage control, and rich peripherals in one chip. Fits Integrated Circuits (ICs), Specialized ICs category. Ideal for legacy support, repairs, and long-running platforms.

Key Features

ARM920T 32-bit core, speed grade up to 400 MHz (suffix “-40” series)

Instruction and data cache typical of ARM920T for faster processing

External memory controller for SDRAM, SRAM, NOR, and NAND flash

Built-in NAND flash controller with hardware ECC

LCD controller for TFT/STN panels, multiple color depths

USB 1.1 Host and Device support

MMC/SD card controller

Camera interface for basic imaging pipelines

Multiple UARTs, I2C, SPI for easy connectivity

Timers, PWM, watchdog, RTC, GPIO

DMA engine for efficient data movement

Touchscreen/ADC support common in this family

Low-power modes and flexible clocking options

Key Advantages

One-chip solution reduces BOM and board complexity

Mature, proven platform with wide ecosystem support

Strong NAND support improves data integrity

Flexible display options for HMI and portable devices

Rich peripherals reduce need for external controllers

Good choice for sustaining legacy designs and field repairs

Packaging

Type: Fine-pitch BGA/FBGA suitable for compact boards (package code 869)

Material: Molded resin with solder ball array on organic substrate; lead-free options vary by lot/date code

Size: Small footprint for handhelds and embedded modules; see datasheet mechanicals for exact dimensions

Pin configuration: High ball-count grid with grouped signals (memory bus, display, USB, MMC/SD, serial interfaces, power/ground)

Thermal characteristics: BGA relies on PCB copper for heat spreading; follow JEDEC guidelines; ensure good vias and thermal paths

Electrical properties: Typical core supply around 1.8 V; I/O typically 3.3 V; external crystal/oscillator needed; full DC/AC specs in datasheet

Package / Case code: 869 (as listed)

Stock and date codes: Quantity 1268; mixed date codes 07+09+10+

RoHS/lead status: Depends on lot/date code; confirm with Y-IC sales for specific compliance

Lifecycle

Status: Legacy ARM9 processor. Commonly NRND/EOL in current supply chains

Discontinuation: Availability may be limited to existing inventory and select lots
