Product Overview

LPC824M201JDH20J is a high-performance 32-bit microcontroller (MCU) from NXP’s LPC82x Series, based on the efficient ARM® Cortex-M0+ core, designed for embedded scenarios requiring high integration, low power consumption, and small size. This product supports a maximum clock frequency of 30 MHz, integrates 32 KB programmable Flash and 8 KB SRAM, and is equipped with rich peripherals such as 18-channel DMA, SCTimer/PWM, 4 I2Cs, 3 USARTs, and 2 SPIs. Adopting a 20-pin TSSOP package (4.4mm body width), it operates within a voltage range of 1.8-3.6 V and a temperature range of -40°C to 105°C, perfectly suitable for space-constrained embedded applications such as sensor gateways, industrial control, and consumer electronics. As the core model of LPC824M201JDH20J, its balanced performance, rich peripherals, and compact package make it an optimal choice for upgrading 8/16-bit MCUs.

Key Features

• Balance of High Performance and Low Power Consumption：30 MHz Cortex-M0+ core with single-cycle multiplier and fast I/O port. Power consumption as low as 90 μA/MHz in low-current mode, supporting four low-power modes (Sleep/Deep-sleep/Power-down/Deep power-down) with a typical power consumption of only 0.2 μA (3.3V/25°C) in Deep power-down mode.
• Highly Integrated Peripheral Combination：Integrates 4 I2Cs (including 1 Fast-mode Plus 1 Mbit/s), 3 USARTs, 2 SPIs, 18-channel DMA controller, and SCTimer/PWM (supporting 6-channel PWM output). No additional expansion chips are required to meet multi-device interconnection and complex control needs.
• Flexible I/O and Precise Acquisition：16 general-purpose GPIO pins (4 high-current outputs of 20 mA) supporting programmable pull-up/pull-down and open-drain modes; 5-channel 12-bit ADC (maximum sampling rate 1.2 Msamples/s) with two independent conversion sequences, suitable for precise sensing acquisition scenarios.
• Powerful Timing and Control Capabilities：SCTimer/PWM supports 32-bit counting and 8 match/capture registers, enabling complex timing control and PWM output; 4-channel Multi-Rate Timer (MRT), Windowed Watchdog Timer (WWDT), and Self-Wake-up Timer (WKT) meet diverse timing requirements.
• High Reliability and Security：Operates within a temperature range of -40°C to 105°C, supports three levels of Code Read Protection (CRP), has ESD protection up to ±3500 V (HBM), Flash erase/write endurance of 100,000 cycles, and data retention for up to 20 years (powered state).
