Product details
Overview
LPC4353JBD208E from NXP Semiconductors is a dual-core ARM Cortex-M4F/M0 microcontroller in LQFP208 package, featuring 512 kB flash (256 kB per bank), 136 kB SRAM, 16 kB EEPROM, IEEE 1588-capable 10/100T Ethernet MAC, two high-speed USB 2.0 interfaces (one with on-chip HS PHY, one with ULPI), and LCD controller - deployed in industrial motor control and embedded audio systems.
For engineers reviewing the LPC4353JBD208E datasheet, LPC4353JBD208E pinout, LPC4353JBD208E application, or LPC4353JBD208E equivalent, key selection criteria include dual-core real-time partitioning, external memory controller support for SDRAM/NOR, quad-SPI Flash Interface (SPIFI) with execute-in-place, and hardware-accelerated SCTimer/PWM for deterministic timing-critical control loops.
Technical Context
The LPC4353JBD208E integrates an ARM Cortex-M4F core (r0p1) running up to 204 MHz with hardware FPU, MPU, NVIC, and ETM/ETB trace, alongside a fully independent ARM Cortex-M0 coprocessor (r0p0) also rated to 204 MHz - enabling asymmetric multiprocessing where the M0 handles peripheral management and the M4 executes real-time DSP or control algorithms.
Its memory subsystem includes dual-bank flash with independent erase/program capability, multiple SRAM blocks (AHB and local) with individual power-down control, 64 kB ROM with boot code and USB stack, and 256-byte battery-backed RTC registers. The AHB multilayer matrix enables concurrent bus access across DMA, peripherals, and cores without arbitration bottlenecks.
