That holds a moderate firmware image — a Modbus RTU stack plus a PID loop, or a simple HMI front-end with a few screens of lookup tables. The 8 KB SRAM is the runtime workspace; it limits the size of data buffers, so if your application queues many CAN or UART messages, check the worst-case stack depth and buffer allocation against this 8 KB ceiling. The part has no external bus, so the firmware and data must fit entirely on-chip. Supply range is 1.65 V to 1.95 V. ## On-chip peripherals and I/O The part integrates an 8-channel, 10-bit SAR ADC for direct sensor readout. Serial connectivity covers I²C, SPI, SSI, SSP, and UART/USART.","metaTitle":"NXP LPC2103FBD48EL ARM7 MCU, 70 MHz, 32 KB Flash, 48-LQFP","metaDescription":"NXP LPC2103FBD48EL 16/32-bit ARM7 MCU, 70 MHz core, 32 KB Flash, 8 KB SRAM, 8-ch 10-bit ADC, -40 to 85 °C, 48-LQFP.
