Product details
Overview
LPC54102J256BD64QL from NXP Semiconductors is a dual-core ARM Cortex-M4/M0+ microcontroller with 256 kB flash, 104 kB SRAM, and integrated peripherals including a 12-bit 5.0 Msamples/sec ADC, SCTimer/PWM, RTC, and three Fast-mode Plus I²C interfaces. It operates up to 150 MHz and supports deep power-down modes with wake-up via USART, SPI, or I²C - ideal for low-power industrial sensor nodes and motor control edge devices.
For engineers reviewing the LPC54102J256BD64QL datasheet, LPC54102J256BD64QL pinout, LPC54102J256BD64QL application, or LPC54102J256BD64QL equivalent, key selection considerations include dual-core real-time task partitioning, 50 GPIOs with configurable pull/resistors and pattern-match interrupt logic, and LQFP64 package compatibility with legacy LPC5410x board layouts.
Technical Context
The LPC54102J256BD64QL integrates two independent 32-bit ARM cores: the Cortex-M4 (with FPU and MPU) and Cortex-M0+ (code- and tool-compatible), both running up to 150 MHz from a shared clock source. Its memory subsystem includes 256 kB on-chip flash (256-byte page erase/write), 96 kB contiguous main SRAM, and 8 kB auxiliary SRAM - all accessible via multilayer AHB matrix with DMA support.
Peripherals are tightly coupled to the DMA controller (22 channels, 20 triggers), enabling zero-CPU-overhead data movement between the 12-channel ADC, USARTs, SPIs, and I²C interfaces. The State-Configurable Timer (SCT/PWM) provides 8 inputs/8 outputs with internal routing to peripherals and supports 13 events/states - enabling complex waveform generation and event-driven state machines without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Cores | Dual ARM Cortex-M4 (FPU/MPU) + Cortex-M0+, both up to 150 MHz - enables asymmetric task partitioning (e.g., M4 for signal processing, M0+ for low-latency I/O handling). |
| Flash / SRAM | 256 kB flash (256-byte page erase); 104 kB total SRAM (96 kB contiguous + 8 kB auxiliary) - sufficient for RTOS + application firmware with buffer space for sensor fusion or communication stacks. |
| ADC | 12-bit, 12-channel, 5.0 Msamples/sec - supports high-speed analog monitoring (e.g., motor current sensing, audio pre-processing) with dual independent conversion sequences. |
| I²C Interfaces | Three Fast-mode Plus I²C-bus interfaces (up to 1 Mbit/s), each supporting High-Speed slave mode (3.4 Mbit/s) - allows direct connection to high-bandwidth sensors and multi-drop bus topologies. |
| GPIO | 50 general-purpose I/O pins with programmable pull-up/pull-down, open-drain, input inverter, and pin-interrupt capability - supports flexible interface adaptation and hardware-level event filtering via pattern-match engine. |
| Power Range | Single 1.62 V to 3.6 V supply with integrated PMU - enables direct battery operation (e.g., 2×Li-ion or 3×AA) without external regulators in portable applications. |
| Package | LQFP64 (10 × 10 × 1.4 mm, SOT314-2) - industry-standard footprint compatible with automated assembly and thermal management in industrial PCBs. |
Pinout & Package
LQFP64 package: plastic low-profile quad flat package with 64 leads, body size 10 × 10 × 1.4 mm (SOT314-2), lead pitch 0.5 mm, RoHS-compliant, operating temperature −40 °C to +105 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–6, 11–13, 17–20, 22–24, 26–30, 32–48, 50–51, 53–64 | GPIO / Peripheral Multiplexed I/O | 50 pins support up to four digital functions (e.g., USART, SPI, I²C, SCT PWM) plus analog input - enables flexible peripheral mapping and pin reuse across design variants. |
| 52 (SWCLK), 53 (SWDIO) | JTAG/SWD Debug Interface | Standard Serial Wire Debug interface with SWO trace output - supports non-intrusive real-time debugging and code profiling without dedicated debug pins. |
| 55 (VSS), 25 (VSS), 9 (VSS), 20 (VSSA), 21 (VREFN) | Ground / Analog Reference Return | Dedicated analog ground (VSSA) and reference return (VREFN) isolate noise-sensitive ADC paths from digital switching currents. |
| 56 (VDD), 8 (VDD), 24 (VDD), 34 (VDD), 23 (VDDA) | Power Supply | Multiple VDD pins reduce IR drop; separate VDDA (analog supply) ensures stable 12-bit ADC performance across load transients. |
