NXP Semiconductors LPC865M201JHI48/0K

Overview

LPC865M201JHI48 from NXP Semiconductors is a 32-bit Arm Cortex-M0+ microcontroller operating at up to 60 MHz, featuring 64 KB flash, 8 KB SRAM, a 12-bit ADC with 12-channel input, two FlexTimers (one with motor control support), and I3C-MIPI interface - deployed in industrial sensor gateways and portable motor-control systems.

For engineers reviewing the LPC865M201JHI48 datasheet, LPC865M201JHI48 pinout, LPC865M201JHI48 application, or LPC865M201JHI48 equivalent, key selection criteria include HVQFN48 package compatibility, 42 GPIO count, I3C/USART/SPI peripheral routing flexibility via switch matrix, and deep power-down wake-up capability on PIO0_4.

Technical Context

The LPC865M201JHI48 implements an Arm Cortex-M0+ r0p1 core with single-cycle I/O, nested vectored interrupt controller (NVIC), and system tick timer. Its AHB multilayer matrix enables concurrent access to flash, SRAM, and peripherals including DMA (16 channels) and CRC engine.

Peripherals are functionally decoupled from physical pins via a programmable switch matrix: USART, SPI, I2C, I3C, FlexTimer, and ADC inputs can be routed to any non-power/non-ground GPIO, while fixed-function pins (e.g., XTALIN/XTALOUT, RESET, SWDIO/SWCLK) retain dedicated roles.

FAQ

What is the maximum CPU frequency supported by the LPC865M201JHI48?

The LPC865M201JHI48 supports a maximum CPU frequency of 60 MHz using its Arm Cortex-M0+ core. This frequency is achievable with the internal Free Running Oscillator (FRO) at 60 MHz, or via PLL multiplication from lower-frequency sources such as the 1–25 MHz crystal oscillator or external clock input. The core operates with a two-stage pipeline and single-cycle multiplier for deterministic execution.

How many GPIO pins are available on the LPC865M201JHI48 in the HVQFN48 package?

The LPC865M201JHI48 in HVQFN48 package provides 42 general-purpose I/O pins. These include PIO0_0 through PIO0_31 and PIO1_0 through PIO1_21, excluding dedicated power, ground, reference, and debug pins. All GPIOs support configurable pull-up/pull-down, open-drain mode, input inverter, and digital filtering - with four pins offering 20 mA high-current source and two pins supporting 20 mA true open-drain sink.

Does the LPC865M201JHI48 support I3C-MIPI, and what are its key capabilities?

Yes, the LPC865M201JHI48 integrates a controller/target I3C-MIPI bus interface compliant with MIPI I3C v1.1. It supports Dynamic Address Assignment (DAA), Hot-Join, and Double Data Rate (DDR) mode, and is fully supported by the general-purpose DMA controller. Unlike I2C, I3C enables higher bandwidth, lower pin count, and built-in command/response protocol - ideal for sensor-rich edge nodes where bus efficiency and scalability matter.

What power modes does the LPC865M201JHI48 support, and how does deep power-down wake-up work?

The LPC865M201JHI48 supports sleep, deep-sleep, power-down, and deep power-down modes. In deep power-down, only the WAKEUP pin (PIO0_4) and Self-Wake-up Timer (WKT) remain active. A LOW-going pulse ≥50 ns on PIO0_4 exits deep power-down and initiates wake-up sequence. Alternatively, WKT can generate timed wake events using FRO, LPOSC, or external clock - enabling sub-μA system standby with precise event scheduling.

Is the LPC865M201JHI48 pin-compatible with other members of the LPC86x family in HVQFN48?

Yes, the LPC865M201JHI48 is pin-compatible with other HVQFN48 variants in the LPC86x family, including LPC864M201JHI48 and LPC862M201JHI48. All share identical pin numbering, electrical characteristics, and switch matrix routing - differing only in flash size, peripheral enablement (e.g., I3C presence), and factory-programmed boot ROM features. No PCB redesign is required when migrating between these variants.
