Product details
Overview
LPC1822JET100E from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller targeting industrial embedded control applications. It operates at up to 180 MHz, integrates 512 kB flash (bank A only), 104 kB SRAM, no Ethernet or LCD controller, one High-speed USB 2.0 host/device interface (USB0), and supports -40 °C to +105 °C operation in TFBGA100 packaging.
For engineers reviewing the LPC1822JET100E datasheet, LPC1822JET100E pinout, LPC1822JET100E application, or LPC1822JET100E equivalent, key selection considerations include its USB0-only connectivity, absence of Ethernet/LCD/EMC, 49 GPIO count, 4-channel ADC support, and TFBGA100 footprint for space-constrained industrial control modules.
Technical Context
The LPC1822JET100E implements the ARM Cortex-M3 r2p1 core with Harvard architecture, 3-stage pipeline, and integrated MPU/NVIC. It uses separate instruction/data buses and includes an internal prefetch unit with speculative branching for deterministic real-time execution.
Its peripheral set centers on USB0 (with on-chip high-speed PHY), dual 10-bit ADCs (4 channels total), SCTimer/PWM subsystem, GIMA crossbar, and four UART/USART interfaces - all accessible via AHB with DMA support. No Ethernet MAC, LCD controller, or external memory controller is present per ordering table data.

FAQ
What is the maximum operating frequency of the LPC1822JET100E?
The LPC1822JET100E operates at a maximum CPU frequency of 180 MHz. This is achieved using the ARM Cortex-M3 core with integrated flash accelerator and three PLLs - one dedicated to CPU clocking. The frequency is fully supported across the full -40 °C to +105 °C temperature range specified for the LPC1822JET100E.
Does the LPC1822JET100E include an Ethernet MAC?
No, the LPC1822JET100E does not include an Ethernet MAC. Per Table 2 in the official NXP datasheet, Ethernet is explicitly marked "no" for this variant. The LPC1822JET100E retains USB0, dual ADCs, SCTimer/PWM, and 49 GPIO but omits Ethernet, LCD, and EMC peripherals to optimize cost and footprint for USB-focused applications.
How much SRAM and flash memory does the LPC1822JET100E have?
The LPC1822JET100E integrates 104 kB of on-chip SRAM and 512 kB of flash memory allocated entirely to Bank A (Bank B is 0 kB). This configuration supports robust RTOS operation, USB descriptor storage, and firmware images while eliminating dual-bank overhead - consistent with its role as a cost-optimized industrial controller variant within the LPC18xx family.
What package type is used for the LPC1822JET100E?
The LPC1822JET100E uses the TFBGA100 package (SOT926-1): a 9 mm × 9 mm × 0.7 mm thin fine-pitch ball grid array with 100 balls and 0.8 mm pitch. This package enables high I/O density in compact industrial modules and is compatible with standard Type II BGA assembly processes.
Can the LPC1822JET100E support USB device and host modes simultaneously?
No, the LPC1822JET100E supports only one USB interface (USB0), which operates in Host/Device/OTG mode - not concurrently. While USB0 can be configured as either host or device depending on firmware, it cannot maintain both roles simultaneously. For dual-role concurrent operation, a second USB interface (e.g., USB1 on LPC1833JET100) would be required.
