NXP Semiconductors LPC18S37JET100E

Overview

LPC18S37JET100E from NXP Semiconductors is a 32-bit ARM Cortex-M3 microcontroller targeting industrial and embedded applications requiring Ethernet connectivity, USB host/device capability, and secure boot. It operates at up to 180 MHz, integrates 1 MB dual-bank flash (512 kB per bank), 136 kB SRAM, and supports -40 °C to +105 °C operation in a TFBGA100 package. Its dual High-speed USB controllers (USB0 with on-chip PHY, USB1 with ULPI interface) and 10/100T Ethernet MAC enable robust wired communication in gateway and edge-node designs.

For engineers reviewing the LPC18S37JET100E datasheet, LPC18S37JET100E pinout, LPC18S37JET100E application, or LPC18S37JET100E equivalent, key selection criteria include its TFBGA100 footprint, absence of LCD controller and QEI, limited to four ADC channels and no motor control PWM-critical for space-constrained, cost-optimized industrial controllers where Ethernet+USB coexistence is required without display or motion control peripherals.

Technical Context

The LPC18S37JET100E implements an ARM Cortex-M3 r2p1 core with Harvard architecture, 3-stage pipeline, and integrated MPU supporting eight memory regions. Its clock system includes three PLLs-one for CPU up to 180 MHz, one dedicated to USB0, and one configurable as audio PLL-enabling independent high-speed peripheral operation without external high-frequency crystals.

Digital subsystems feature a State Configurable Timer/PWM (SCTimer/PWM) with event-driven flexibility, Global Input Multiplexer Array (GIMA) for cross-peripheral signal routing, and an External Memory Controller (EMC) supporting SDRAM, NOR flash, and SRAM. Analog resources include two 10-bit ADCs (400 kSamples/s, shared 4-channel input) and one 10-bit DAC (400 kSamples/s), all with DMA support.

FAQ

What is the maximum operating frequency of the LPC18S37JET100E?

The LPC18S37JET100E features an ARM Cortex-M3 processor capable of running at up to 180 MHz. This maximum frequency is achieved using the on-chip PLLs and requires proper decoupling, thermal management, and voltage regulation within the 2.4 V to 3.6 V supply range. The LPC18S37JET100E datasheet specifies this rating under full industrial temperature conditions (-40 °C to +105 °C), confirming sustained performance in demanding environments.

Does the LPC18S37JET100E include an LCD controller?

No, the LPC18S37JET100E does not include an LCD controller. According to Table 2 in the official NXP datasheet, the "LCD" column for LPC18S37JET100E is marked "no", distinguishing it from higher-pin-count variants like LPC18S57JET256. This omission reduces die size and cost, making the LPC18S37JET100E suitable for applications where display functionality is handled externally or omitted entirely.

How many ADC channels does the LPC18S37JET100E support?

The LPC18S37JET100E supports four analog input channels, shared between its two 10-bit ADCs (ADC0 and ADC1). As confirmed in Table 2 of the NXP datasheet, the "ADC channels" value is "4", and the pin description confirms that ADC inputs are multiplexed-each physical channel connects to both ADCs, enabling simultaneous sampling or redundancy without additional external circuitry.

What USB interfaces are available on the LPC18S37JET100E?

The LPC18S37JET100E integrates two High-speed USB 2.0 interfaces: USB0 supports Host/Device/OTG modes with an on-chip high-speed PHY, while USB1 supports Host/Device modes with ULPI interface to an external high-speed PHY. Per Table 2, USB1 lacks OTG capability and has no on-chip PHY-requiring external PHY silicon but offering flexibility in USB topology design.

Is the LPC18S37JET100E pin-compatible with other LPC18Sxx variants?

No, the LPC18S37JET100E is not pin-compatible with other LPC18Sxx variants due to its TFBGA100 package (100 balls), whereas LPC18S57JET256 uses LBGA256 (256 balls) and LPC18S37JBD144 uses LQFP144 (144 leads). Pin functions also differ significantly across packages-even identical pin names (e.g., P0_0) map to different ball positions and may have variant-specific alternate functions not present in the LPC18S37JET100E.
