The 80 KB Flash is sized for firmware that fits in a single bank — think motor commutation tables, Modbus stacks, or simple HMI logic. The 8 KB RAM handles a few communication buffers and local variables; if your application needs a large frame buffer or extensive data logging, you'll want to step up to a part with more SRAM. The on-chip 8-channel 10-bit ADC covers basic analog sensing — temperature, current, voltage — without an external converter. Serial connectivity is a strong point: I2C, SPI, UART/USART, IrDA, Microwire, SSI, and SSP are all on board. That means you can talk to most common sensors, displays, and peripheral ICs directly.

Product details
Frequently asked questions
What is the core of LPC1225FBD48/321,1?
It uses a 32-bit ARM Cortex-M0 core running at 45 MHz.
What package is LPC1225FBD48/321,1 in?
It comes in a 48-LQFP package (7x7 mm), surface-mount.
What is the difference between LPC1225 and LPC1224?
The LPC1225 offers 80 KB Flash and 8 KB RAM, while the LPC1224 typically has 48 KB Flash and 4 KB RAM — the LPC1225 gives you more memory headroom for larger firmware and data buffers. Both share the same Cortex-M0 core and 48-LQFP package option.
