NXP Semiconductors LPC2917FBD144/01/,

Overview

LPC2917FBD144/01 from NXP Semiconductors is an ARM968E-S-based 32-bit microcontroller operating at up to 80 MHz, featuring dual CAN 2.0B controllers, two hardware LIN 2.0 masters, 512 kB on-chip flash, and 80 kB total RAM (including 16 kB ITCM + 16 kB DTCM + 48 kB SRAM). It targets automotive body control modules requiring real-time communication, deterministic interrupt response, and mixed-signal integration.

For engineers reviewing the LPC2917FBD144/01 datasheet, LPC2917FBD144/01 pinout, LPC2917FBD144/01 application, or LPC2917FBD144/01 equivalent, key selection considerations include CAN/LIN coexistence, 1.8 V core / 3.3 V I/O dual-supply operation, 144-pin LQFP package with 108 GPIOs, and support for in-system flash programming via CAN.

Technical Context

The LPC2917FBD144/01 implements a hierarchical clock architecture with independent base clocks (e.g., BASE_SYS_CLK, BASE_IVNSS_CLK, BASE_UART_CLK) routed through the Clock Generation Unit (CGU) and Power Management Unit (PMU), enabling per-peripheral clock gating and dynamic frequency scaling. Its AHB-to-APB bridges include write-ahead buffers to decouple CPU writes from peripheral timing.

It integrates two separate memory subsystems: tightly coupled memories (ITCM/DTCM) for low-latency code/data execution, and distributed SRAM blocks (32 kB + 16 kB) accessible via dedicated AHB slaves. The external static memory controller supports 32-bit data width and up to 24-bit addressing across eight banks.

FAQ

What is the maximum operating frequency of the LPC2917FBD144/01?

The LPC2917FBD144/01 operates at a maximum CPU frequency of 80 MHz, achieved via its on-chip PLL driven by a 10–25 MHz crystal oscillator. This frequency applies to the ARM968E-S core, AHB system bus, and TCM interfaces. Peripheral clocks (e.g., UART, SPI, CAN) are derived independently via the CGU and may run at lower frequencies to optimize power consumption.

Does the LPC2917FBD144/01 support in-system programming via CAN?

Yes, the LPC2917FBD144/01 supports in-system programming (ISP) via CAN, as confirmed in Section 2.3 of the datasheet. This capability enables field firmware updates without JTAG hardware, using the built-in bootloader. The CAN interface must be configured in the application firmware to initiate ISP mode, and flash protection settings must permit external programming.

How many ADC channels does the LPC2917FBD144/01 provide, and what is their resolution and speed?

The LPC2917FBD144/01 integrates two independent 10-bit ADCs (ADC1 and ADC2), providing up to 16 total analog input channels. Each ADC achieves a minimum conversion time of 2.44 µs per channel. Both ADCs include per-channel hardware compare functionality to generate interrupts only when input values cross user-defined thresholds-reducing CPU polling overhead significantly.

What are the power supply requirements for the LPC2917FBD144/01?

The LPC2917FBD144/01 requires two distinct power supplies: a 1.8 V ±5 % supply (VDD(CORE)) for the ARM968E-S core, TCMs, and AHB infrastructure; and a 2.7–3.6 V supply (VDD(IO)) for all I/O pins, peripherals, and analog blocks. I/O pins are 5.5 V-tolerant, allowing direct interfacing with legacy 5 V logic without level shifters.

Is the LPC2917FBD144/01 pin-compatible with other devices in the LPC29xx family?

Yes, the LPC2917FBD144/01 shares identical pinout and package (LQFP144, SOT486-1) with the LPC2919FBD144 and LPC2927FBD144. All three devices are hardware-compatible at the board level; differences are limited to flash size (512 kB vs. 768 kB) and minor feature sets-enabling drop-in replacement during design-in or production ramp.
