NXP Semiconductors LPC4310FET100,551

Overview

LPC4310FET100,551 from NXP Semiconductors is a flashless dual-core ARM Cortex-M4/M0 microcontroller targeting resource-constrained embedded control applications. It integrates a 204 MHz Cortex-M4 main processor with hardware FPU and NVIC, a 204 MHz Cortex-M0 coprocessor for offload tasks, 168 kB on-chip SRAM (distributed across AHB and local banks), no Ethernet or LCD controller, and only USB1 (Host/Device) without integrated high-speed PHY-requiring external ULPI PHY. It is used in cost-sensitive industrial sensor nodes and low-complexity motor control modules where deterministic real-time response and peripheral flexibility are critical.

For engineers reviewing the LPC4310FET100,551 datasheet, LPC4310FET100,551 pinout, LPC4310FET100,551 application, or LPC4310FET100,551 equivalent, key selection criteria include its TFBGA100 package (9 × 9 mm, 0.7 mm height), absence of Ethernet/USB0/LCD, 4-channel 10-bit ADC support, 49 GPIO pins, and dual-core asymmetric execution capability for task partitioning between M4 and M0 subsystems.

Technical Context

The LPC4310FET100,551 implements a tightly coupled dual-core architecture: the Cortex-M4 executes primary application code with DSP/FP instructions and full debug visibility, while the Cortex-M0 handles background I/O management, sensor polling, or safety monitoring-communicating via shared SRAM and event router. Its clock system uses three independent PLLs: one for CPU core clocks up to 204 MHz, one dedicated to USB1 (via ULPI), and one configurable for audio timing.

Peripherals are segmented across AHB and APB bridges with GIMA enabling flexible cross-triggering between SCTimer/PWM, ADCs, and timers. The device lacks Ethernet MAC, LCD controller, and USB0 PHY-confirmed by Table 2-and supports only four ADC input channels (shared between ADC0 and ADC1), two SSP controllers, and one Fast-mode Plus I²C interface with 1 Mbit/s capability.

FAQ

What is the maximum operating frequency of the LPC4310FET100,551?

The LPC4310FET100,551 supports a maximum CPU frequency of 204 MHz for both the ARM Cortex-M4 and Cortex-M0 cores. This is achieved using an internal PLL driven by the 12 MHz IRC oscillator or an external crystal (1–25 MHz). The device's performance is validated across its full industrial temperature range (-40°C to +85°C) and 2.2–3.6 V supply voltage window.

Does the LPC4310FET100,551 include on-chip flash memory?

No, the LPC4310FET100,551 is a flashless microcontroller. It relies entirely on its 168 kB of on-chip SRAM for code and data execution, and boots from external memory (e.g., SPI Flash via SPIFI) or ROM-resident bootloader. This architecture reduces cost, improves security via external encrypted storage, and avoids flash wear-out in high-update-rate applications.

Which USB interfaces are supported on the LPC4310FET100,551?

The LPC4310FET100,551 supports only USB1: a High-speed USB 2.0 Host/Device interface with DMA support, on-chip full-speed PHY, and ULPI interface for connection to an external high-speed PHY. USB0 (Host/Device/OTG with integrated HS PHY) and Ethernet are explicitly excluded per Table 2 of the datasheet.

How many ADC input channels does the LPC4310FET100,551 provide?

The LPC4310FET100,551 integrates two 10-bit ADCs (ADC0 and ADC1) with a combined total of four input channels. These channels are multiplexed across dedicated and shared pins, and support a maximum conversion rate of 400 kSamples/s. No DAC or analog comparator peripherals are included.

What is the package type and pin count of the LPC4310FET100,551?

The LPC4310FET100,551 is packaged in a TFBGA100 (SOT926-1): a 100-ball thin fine-pitch ball grid array with 9 × 9 mm body size, 0.7 mm height, and 0.65 mm ball pitch. It includes an exposed thermal pad for enhanced thermal dissipation in compact industrial enclosures.
