NXP Semiconductors LPC1837JET100E

Overview

LPC1837JET100E from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller operating at up to 180 MHz, featuring 1 MB dual-bank flash, 136 kB SRAM, Ethernet MAC with IEEE 1588 support, two High-speed USB interfaces (one OTG-capable), and a TFBGA100 package rated for -40 °C to +105 °C. It targets industrial control and e-metering systems requiring deterministic real-time performance and secure connectivity.

For engineers reviewing the LPC1837JET100E datasheet, LPC1837JET100E pinout, LPC1837JET100E application, or LPC1837JET100E equivalent, key selection criteria include its 100-ball TFBGA footprint, absence of LCD controller and QEI, limited ADC channels (4), and USB1 without ULPI-critical for compact, cost-optimized embedded designs with Ethernet and dual USB host/device needs.

Technical Context

The LPC1837JET100E implements an ARM Cortex-M3 r2p1 core with Harvard architecture, 3-stage pipeline, and integrated MPU/NVIC for deterministic interrupt handling. Its memory subsystem includes dual-bank flash with accelerator, 136 kB AHB-accessible SRAM split across multiple blocks, and 16 kB EEPROM-all accessible via high-bandwidth AHB matrix.

Digital peripherals are routed through the Global Input Multiplexer Array (GIMA) and State Configurable Timer/PWM (SCTimer/PWM), enabling flexible event-driven I/O coordination. Clock generation uses three PLLs: one for CPU up to 180 MHz, one dedicated to USB0, and one configurable as audio PLL-while the RTC domain operates independently on battery backup.

FAQ

What is the maximum CPU frequency supported by the LPC1837JET100E?

The LPC1837JET100E supports a maximum CPU frequency of 180 MHz using its ARM Cortex-M3 core. This is achieved via an internal PLL fed by the main crystal oscillator or IRC, with flash accelerator enabled to sustain full-speed execution from on-chip memory. The LPC1837JET100E maintains this performance across its full -40 °C to +105 °C operating range.

Does the LPC1837JET100E include an LCD controller?

No, the LPC1837JET100E does not include an LCD controller. Per Table 2 in the official datasheet, LCD support is explicitly marked "no" for all LPC183x variants in the TFBGA100 package-including the LPC1837JET100E. This omission reduces die size and cost while maintaining Ethernet, USB, and analog peripherals essential for non-display industrial applications.

How many ADC channels are available on the LPC1837JET100E?

The LPC1837JET100E integrates two 10-bit ADCs (ADC0 and ADC1) with a total of four analog input channels. As confirmed in Table 2, the TFBGA100 package variants-including the LPC1837JET100E-support only four ADC channels, shared between both converters. Each channel is accessible via dedicated or multiplexed pins as defined in the pin description table.

What USB capabilities does the LPC1837JET100E provide?

The LPC1837JET100E provides two USB interfaces: USB0 supports Host/Device/OTG with an integrated high-speed PHY, while USB1 supports Host/Device only with an on-chip full-speed PHY and no ULPI interface. This configuration is verified in Table 2, where USB1 is listed as "yes/no" for the LPC1837JET100E-indicating FS-only operation without external HS PHY support.

Is the LPC1837JET100E pin-compatible with other LPC18xx TFBGA100 variants?

Yes, the LPC1837JET100E shares identical pinout and package (TFBGA100, SOT926-1) with all other LPC18xx family members in the same package-including LPC1833JET100, LPC1827JET100, and LPC1817JET100. Pin functions are consistent across variants; differences lie solely in enabled peripherals (e.g., Ethernet, LCD, QEI), which are disabled or unconnected in silicon-not via pin remapping.
