NXP Semiconductors LPC1833JET100E

Overview

LPC1833JET100E from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller designed for industrial and connected embedded systems. It operates at up to 180 MHz, integrates 512 kB flash (256 kB per bank), 136 kB SRAM, dual 10-bit ADCs (400 kSamples/s), Ethernet MAC with IEEE 1588 support, and two High-speed USB interfaces - one with on-chip HS PHY (USB0), one with ULPI interface (USB1). It targets resource-constrained, real-time control applications requiring deterministic timing and peripheral integration.

For engineers reviewing the LPC1833JET100E datasheet, LPC1833JET100E pinout, LPC1833JET100E application, or LPC1833JET100E equivalent, key selection considerations include its TFBGA100 package (9 × 9 mm), -40 °C to +105 °C temperature grade, absence of LCD controller and motor control PWM, and verified support for RMII Ethernet, SPIFI, SCTimer/PWM, and C_CAN 2.0B - critical for industrial gateways and metering designs.

Technical Context

The LPC1833JET100E implements an ARM Cortex-M3 r2p1 core with Harvard architecture, 3-stage pipeline, and integrated MPU/NVIC. Its clock system uses three PLLs: one for CPU up to 180 MHz, one dedicated to USB0, and one configurable as audio PLL - enabling independent domain scaling without high-frequency crystals.

Digital subsystems include a State-Configurable Timer/PWM (SCTimer/PWM) with event-driven state machines, Global Input Multiplexer Array (GIMA) for flexible peripheral signal routing, and an External Memory Controller (EMC) supporting SDRAM, NOR flash, and SRAM - all accessible via AHB multilayer matrix for concurrent DMA and CPU access.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Compared with LPC1853JET100, LPC1833JET100 removes LCD/motor PWM logic to reduce cost and power in headless applications; compared with LPC4357JET256, it retains Ethernet MAC and smaller TFBGA100 packaging but lacks dual-core and FPU - making it the optimal choice for deterministic, space-constrained industrial networking.

FAQ

What is the maximum operating frequency of the LPC1833JET100E?

The LPC1833JET100E operates at a maximum CPU frequency of 180 MHz, achieved via its on-chip PLL system. This frequency is fully supported across the full -40 °C to +105 °C temperature range and 2.4 V to 3.6 V supply voltage, as validated in NXP's characterization testing and documented in the LPC185X_3X_2X_1X datasheet Rev. 5.3.

Does the LPC1833JET100E include an LCD controller?

No, the LPC1833JET100E does not include an LCD controller. Per Table 2 in the official datasheet, LCD support is explicitly marked "no" for all LPC183x variants including LPC1833JET100E. This distinguishes it from LPC185x parts (e.g., LPC1853JET100), which integrate a full LCD controller supporting up to 1024×768 resolution.

How many ADC channels does the LPC1833JET100E support?

The LPC1833JET100E integrates two independent 10-bit ADCs (ADC0 and ADC1) with a combined total of eight analog input channels. Each channel is shared between both ADCs (e.g., ADC0_0 and ADC1_0 are tied), enabling simultaneous sampling or redundancy - with a maximum conversion rate of 400 kSamples/s per ADC as specified in Section 2.2 of the datasheet.

What USB interfaces are available on the LPC1833JET100E?

The LPC1833JET100E features two High-speed USB 2.0 interfaces: USB0 supports Host/Device/OTG modes with an integrated on-chip high-speed PHY; USB1 supports Host/Device modes with a ULPI interface for connection to an external high-speed PHY. USB1 does not support OTG, and neither interface includes a full-speed PHY on-die except for USB0's integrated HS PHY.

Is the LPC1833JET100E pin-compatible with other LPC18xx variants in TFBGA100?

Yes, all LPC18xx parts in the TFBGA100 package - including LPC1833JET100E, LPC1837JET100, LPC1823JET100, and LPC1813JET100 - share identical pinouts and ball assignments per Figure 3 (Pin configuration TFBGA100 package) in the datasheet. Functional differences (e.g., Ethernet presence, ADC count) are implemented internally and do not affect mechanical or electrical pin compatibility.
