Product details
Overview
LPC1812JET100E from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller designed for industrial embedded control applications. It operates at up to 180 MHz, integrates 512 kB flash (dual-bank), 104 kB SRAM, and supports -40 °C to +105 °C operation. Key peripherals include dual 10-bit ADCs (400 kSamples/s), SCTimer/PWM subsystem, USB0 Host/Device/OTG with on-chip PHY, and TFBGA100 packaging for space-constrained designs.
For engineers reviewing the LPC1812JET100E datasheet, LPC1812JET100E pinout, LPC1812JET100E application, or LPC1812JET100E equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases, and validated alternative options - all grounded in NXP's official LPC185x/3x/2x/1x Rev. 5.3 documentation.
Technical Context
The LPC1812JET100E implements an ARM Cortex-M3 r2p1 core with Harvard architecture, 3-stage pipeline, and integrated MPU/NVIC. It lacks Ethernet MAC, LCD controller, and motor control PWM - distinguishing it from higher-tier LPC18xx variants per Table 2 of the datasheet.
Its peripheral set includes two High-speed USB interfaces (USB0 with on-chip HS PHY; USB1 with ULPI-only support), quad SPI Flash Interface (SPIFI) up to 52 MB/s, four 550 UARTs, two SSP controllers, one Fast-mode Plus I²C, two I²S, C_CAN 2.0B, SD/MMC, and a State-configurable Timer/PWM (SCTimer/PWM) subsystem on AHB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3 r2p1, 180 MHz max - enables deterministic real-time control with low-latency interrupt handling. |
| Memory | 512 kB dual-bank flash (0 kB bank B), 104 kB SRAM, 16 kB EEPROM - supports secure firmware updates and data logging without external storage. |
| Analog | Dual 10-bit ADCs, 400 kSamples/s, 4 channels total - sufficient for sensor monitoring in industrial HMI or power supply feedback loops. |
| USB | USB0: HS Host/Device/OTG with on-chip PHY; USB1: HS Host/Device via ULPI only - enables dual-role connectivity with minimal external components for USB0. |
| Package | TFBGA100, 9 × 9 × 0.7 mm, 0.5 mm pitch - compact footprint ideal for portable industrial gateways and space-limited edge nodes. |
| Temperature Range | -40 °C to +105 °C (industrial grade) - qualified for deployment in harsh environments including motor drives and e-metering enclosures. |
| Power Supply | Single 3.3 V (2.4–3.6 V) rail with on-chip voltage regulator - simplifies power design and eliminates need for external core LDO. |
Pinout & Package
Package: TFBGA100 (SOT926-1), plastic thin fine-pitch ball grid array, 100 balls, 9 mm × 9 mm × 0.7 mm body, 0.5 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0_0 | I/O (GPIO0[0], SSP1_MISO, ENET_RXD1, I2S0_TX_WS) | Multi-function digital I/O; default GPIO; supports SPI slave interface or audio word select timing. |
| P1_7 | I/O (GPIO1[0], U1_DSR, CTOUT_13, EMC_D0) | GPIO with UART modem control input and memory data bus line - enables flexible peripheral routing in compact layouts. |
| P1_15 | I/O (GPIO0[2], U2_TXD, ENET_RXD0, T0_MAT1, EMC_D8) | Shared UART TX and Ethernet RX signal - requires careful PCB routing separation to avoid noise coupling in mixed-signal designs. |
| P1_19 | I/O (ENET_TX_CLK/REF_CLK, SSP1_SCK, CLKOUT, I2S0_RX_MCLK) | Clock domain multiplexing: serves as Ethernet reference clock, SPI clock, or audio master clock - demands precise clock tree planning. |
| VDDA | Analog Power Supply | 3.3 V analog rail for ADC/DAC; must be filtered separately from digital VDD to maintain 10-bit accuracy. |
| VSSA | Analog Ground | Dedicated analog return path; requires star grounding near ADC pins to minimize quantization error. |
Key Features
| Feature | Design Value |
|---|---|
| State Configurable Timer/PWM (SCTimer) | Hardware-based event-driven timer subsystem enabling complex waveform generation (e.g., multi-phase PWM) without CPU overhead. |
| Global Input Multiplexer Array (GIMA) | Enables dynamic routing of GPIO, timer, ADC, and SCT events across AHB peripherals - reduces software polling and improves real-time response. |

FAQ
What is the maximum operating frequency of the LPC1812JET100E?
The LPC1812JET100E features an ARM Cortex-M3 core rated for up to 180 MHz operation. This frequency is achievable under specified voltage (2.4–3.6 V) and temperature (-40 °C to +105 °C) conditions, as confirmed in Section 2 of the NXP LPC185x/3x/2x/1x datasheet Rev. 5.3. The core includes a prefetch unit and speculative branching to sustain throughput at this rate.
Does the LPC1812JET100E include an Ethernet MAC?
No, the LPC1812JET100E does not include an Ethernet MAC. Per Table 2 in the official datasheet, Ethernet is explicitly marked "no" for this variant. This distinguishes it from LPC183x/5x parts and confirms its targeting toward non-networked industrial control and metering applications where USB or serial connectivity suffices.
What USB capabilities does the LPC1812JET100E support?
The LPC1812JET100E supports two USB interfaces: USB0 provides High-speed Host/Device/OTG with an integrated on-chip PHY; USB1 supports High-speed Host/Device functionality exclusively via ULPI interface - requiring an external PHY. This configuration is documented in Table 2 and Section 2.4 of the NXP datasheet.
How much SRAM and flash memory does the LPC1812JET100E have?
The LPC1812JET100E integrates 512 kB of on-chip flash memory (configured as 512 kB Bank A, 0 kB Bank B) and 104 kB of SRAM. These values are explicitly listed in Table 2 of the NXP LPC185x/3x/2x/1x datasheet Rev. 5.3 and align with its positioning as a mid-tier member of the LPC18xx family.
Is the LPC1812JET100E pin-compatible with other TFBGA100 LPC18xx variants?
Yes, the LPC1812JET100E shares the same TFBGA100 package (SOT926-1) and pinout with other JET100-suffixed LPC18xx parts such as LPC1833JET100 and LPC1823JET100. Pin compatibility is confirmed by identical ball mappings in Figures 3 and Table 3 of the datasheet, enabling hardware reuse across variants with differing peripheral enablement.
