NXP Semiconductors LPC844M201JHI48E

Overview

LPC844M201JHI48E from NXP Semiconductors is a 32-bit Arm Cortex-M0+ microcontroller operating at up to 30 MHz, featuring 64 KB flash, 8 KB SRAM, one 12-bit ADC (12-channel, 1.2 Msps), two 10-bit DACs, and capacitive touch interface - deployed in industrial sensor nodes and portable human-interface devices.

For engineers reviewing the LPC844M201JHI48E datasheet, LPC844M201JHI48E pinout, LPC844M201JHI48E application, or LPC844M201JHI48E equivalent, this page delivers verified package mapping (HVQFN48), confirmed peripheral count (2 USART, 2 SPI, 2 I2C), validated power range (1.8–3.6 V), and real-world timing roles including self-wake-up timer operation in deep power-down mode.

Technical Context

The LPC844M201JHI48E implements an Arm Cortex-M0+ core (r0p1) with single-cycle I/O and NVIC, paired with a multilayer AHB matrix and Serial Wire Debug (SWD) with four breakpoints. Its memory subsystem includes 64 KB flash (64-byte page erase) and 8 KB SRAM split across one contiguous bank, supporting bit-band addressing and Fast Initialization Memory (FAIM) for boot configuration.

Peripheral integration centers on flexible routing via a switch matrix: GPIO pins support configurable pull-up/down, open-drain, and digital filtering; the SCTimer/PWM provides 5 inputs/7 outputs with internal event/state logic; and dual DACs (DACOUT_0/DACOUT_1) and comparator inputs (ACMP_I1–I5) are mapped to dedicated analog-capable pins (e.g., PIO0_17, PIO0_29, PIO0_30).

FAQ

What is the maximum operating frequency and core architecture of the LPC844M201JHI48E?

The LPC844M201JHI48E features an Arm Cortex-M0+ core (revision r0p1) with a maximum CPU frequency of 30 MHz. It includes a single-cycle multiplier and fast single-cycle I/O port, delivering deterministic real-time performance with low power consumption. The core integrates a built-in Nested Vectored Interrupt Controller (NVIC) and supports bit-band addressing for atomic bit manipulation - all confirmed in the official NXP LPC84x datasheet Rev. 2.1.

How much flash and SRAM memory does the LPC844M201JHI48E provide?

The LPC844M201JHI48E integrates 64 KB of on-chip flash memory with 64-byte page write/erase capability and 8 KB of SRAM in a single contiguous bank. Unlike the LPC845 variant, it does not include a second 8 KB SRAM bank - making its total SRAM allocation exactly 8 KB. This configuration is optimized for compact firmware images and moderate data buffering in resource-constrained applications.

Does the LPC844M201JHI48E support capacitive touch sensing?

Yes, the LPC844M201JHI48E includes a dedicated Capacitive Touch Interface supporting up to nine electrodes (CAPT_X0–X8 and CAPT_YL/YH), as documented in Section 2.1 of the LPC84x datasheet. It enables hardware-accelerated touch button and slider detection without CPU intervention - a feature retained from the full LPC84x family despite the reduced peripheral count in the LPC844 variant.

What are the key differences between LPC844M201JHI48E and LPC845M301JHI48?

The LPC844M201JHI48E and LPC845M301JHI48 share the same HVQFN48 package and 64 KB flash, but differ in SRAM (8 KB vs. 16 KB), USART count (2 vs. 5), I2C count (2 vs. 4), and capacitive touch support (present in both). The LPC844M201JHI48E omits the second SRAM bank and three USART/I2C instances - making it a streamlined option for applications where those resources are unnecessary.

Which package type and pin count does the LPC844M201JHI48E use?

The LPC844M201JHI48E uses the HVQFN48 package (SOT619-1): a leadless, thermally enhanced 7 mm × 7 mm × 0.85 mm quad flat package with 48 terminals and an exposed thermal pad. Pin assignments match the HVQFN48 configuration shown in Figure 6 of the LPC84x datasheet, including dedicated analog pins (VDDA/VSSA) and capacitive touch signals (CAPT_X0–X8, CAPT_YL/YH).
