NXP Semiconductors LPC4313JET100E

Overview

LPC4313JET100E from NXP Semiconductors is a dual-core ARM Cortex-M4F/M0 microcontroller targeting industrial control and embedded connectivity applications. It operates at up to 204 MHz, integrates 512 kB flash (256 kB per bank), 104 kB on-chip SRAM, 16 kB EEPROM, two 10-bit ADCs (400 kSamples/s), one 10-bit DAC, and supports USB 2.0 Host/Device (no OTG) and C_CAN 2.0B interfaces - all in a 100-ball TFBGA package.

For engineers reviewing the LPC4313JET100E datasheet, LPC4313JET100E pinout, LPC4313JET100E application, or LPC4313JET100E equivalent, key selection criteria include its dual-core real-time partitioning capability, absence of Ethernet/LCD/USB OTG, limited GPIO count (49 pins), and TFBGA100 footprint suitability for space-constrained industrial sensor nodes and power management modules.

Technical Context

The LPC4313JET100E implements a tightly coupled dual-core architecture: the Cortex-M4F handles high-performance signal processing and real-time control with hardware FPU and MPU, while the Cortex-M0 co-processor offloads peripheral management and deterministic I/O handling at up to 204 MHz. Both cores share memory via AHB multilayer matrix but operate with independent debug interfaces (SWD/JTAG).

Its peripheral set is trimmed for cost-sensitive applications: no Ethernet MAC, no LCD controller, no USB OTG, and only one USB 2.0 interface (USB0) with on-chip full-speed PHY and ULPI support for external high-speed PHY - unlike higher variants. The External Memory Controller (EMC) remains fully functional, supporting NOR flash, SRAM, and SDRAM expansion.

FAQ

What is the maximum operating frequency of the LPC4313JET100E?

The LPC4313JET100E supports a maximum CPU frequency of 204 MHz for both the ARM Cortex-M4F and Cortex-M0 cores. This performance level is achieved using internal PLLs fed from either an external crystal (1–25 MHz) or the 12 MHz internal RC oscillator, with voltage regulation provided by the on-chip DC-DC converter across the 2.4 V to 3.6 V supply range.

Does the LPC4313JET100E include Ethernet or LCD controller functionality?

No, the LPC4313JET100E does not include Ethernet MAC or LCD controller peripherals. As confirmed in Table 2 of the datasheet, these features are explicitly omitted in the LPC431x series. The LPC4313JET100E retains USB, CAN, ADC, DAC, and EMC - making it suitable for applications where networked display or wired Ethernet is unnecessary.

How many GPIO pins are available on the LPC4313JET100E in TFBGA100 package?

The LPC4313JET100E provides 49 GPIO pins in the TFBGA100 package, as specified in Table 2 of the datasheet. These are distributed across multiple port groups (P0–P1, PA–PF) and support configurable pull-up/pull-down resistors, edge/level-sensitive interrupts, and DMA-capable access via AHB bus addressing - enabling efficient peripheral interfacing in resource-constrained designs.

What memory resources are integrated into the LPC4313JET100E?

The LPC4313JET100E integrates 512 kB of on-chip flash memory (split into two 256 kB banks), 104 kB of SRAM, 16 kB of EEPROM, 64 kB of ROM containing boot code and USB/SD/MMC drivers, and 64-bit + 256-bit OTP memory. This memory architecture supports secure firmware updates, persistent configuration storage, and real-time data buffering without external memory components.

Is the LPC4313JET100E pin-compatible with other LPC43xx TFBGA100 variants?

Yes, the LPC4313JET100E shares identical pinout and package dimensions (TFBGA100, SOT926-1) with other LPC43xx devices in the same package, including LPC4333JET100 and LPC4323JET100. However, peripheral availability differs - for example, Ethernet and LCD signals are no-connect on LPC4313JET100E - so PCB design must align with the specific variant's feature set.
