Product details

150 MHz Cortex-M33 with 256 KB Flash — mid-range industrial MCU

The NXP LPC5516JBD64E is a 32-bit ARM Cortex-M33 single-core microcontroller running at 150 MHz, with 256 KB of Flash program memory and 96 KB of SRAM. It sits in the LPC551x series, positioned for real-time control and communication tasks that need a balance of processing throughput and peripheral integration — motor drives, industrial fieldbus gateways, and sensor fusion nodes. The Cortex-M33 core includes a single-cycle multiply-accumulate unit and hardware divide, plus optional TrustZone for security-sensitive code isolation. Operating temperature range is -40 to 105°C.

Connectivity includes CANbus, Flexcomm (configurable as SPI, I²C, or UART/USART), and full-speed USB. I²S and PWM are also on-chip. The 36 GPIO pins are available on the 64-HTQFP package, which has an exposed pad for thermal dissipation.

The part is ROHS3 compliant.

Frequently asked questions

What is the closest pin-compatible alternative to LPC5516JBD64E?

The LPC5526JBD64 is pin-compatible — same 64-HTQFP footprint and peripheral map, but with 512 KB Flash and 256 KB RAM. The LPC5514JBD64 (128 KB Flash) is also pin-compatible for a cost-reduced BOM.

Does LPC5516JBD64E have an internal voltage regulator for 3.3V operation?

Yes, the LPC5516JBD64E includes an internal voltage regulator that allows operation from a 3.3 V supply. The VDD range is 1.8 V to 3.6 V, so a single 3.3 V rail powers the core and I/O without an external LDO.

What is the difference between LPC5516 and LPC5514?

The LPC5516 has 256 KB Flash and 96 KB RAM; the LPC5514 has 128 KB Flash and 64 KB RAM. Both share the same 150 MHz Cortex-M33 core, package options, and peripheral set — the difference is memory density for firmware and data buffers.

Is LPC5516JBD64E compatible with LPC55S16?

The LPC55S16 includes a hardware security sub-system (crypto engine, secure boot) that the LPC5516 lacks. The pinout and package are the same, but firmware that relies on security features will not run on the LPC5516.
