Product details
Overview
LPC2919FBD144/01 from NXP Semiconductors is an ARM968E-S-based 32-bit microcontroller operating at up to 80 MHz, featuring dual CAN 2.0B controllers, two LIN 2.0 master interfaces, 768 kB on-chip flash, 80 kB RAM (including 16 kB ITCM and 16 kB DTCM), and 108 GPIOs. It targets automotive body control modules, industrial gateway nodes, and CAN/LIN networked sensor hubs requiring real-time deterministic communication.
For engineers reviewing the LPC2919FBD144/01 datasheet, LPC2919FBD144/01 pinout, LPC2919FBD144/01 application, or LPC2919FBD144/01 equivalent, key selection criteria include CAN/LIN coexistence capability, dual 10-bit ADCs with 2.44 µs conversion time, 144-pin LQFP package with 3.3 V I/O and 1.8 V core supply, and support for in-system flash programming via CAN.
Technical Context
The LPC2919FBD144/01 implements a hierarchical clock architecture with independent base clocks (e.g., BASE_SYS_CLK, BASE_IVNSS_CLK) feeding 20+ branch clocks-enabling per-peripheral clock gating for power optimization. Its ARM968E-S core uses a five-stage pipeline with Thumb/ARM instruction set dual-mode execution and separate TCM interfaces for deterministic real-time response.
Memory subsystem includes 768 kB flash with 128-bit interface and dual 128-bit buffers, two embedded SRAM blocks (32 kB + 16 kB), and tightly coupled memories (16 kB ITCM, 16 kB DTCM). Peripheral interconnect uses AHB for high-speed core-to-memory paths and APB for low-bandwidth peripherals, with write-ahead buffering on AHB-to-APB bridges.
