[Usage] Single Chip Circuit

[Performance Parameters] The LPC2131 is a 32/16-bit ARM7TDMI-S microcontroller built into a compact LQFP64 package. It features 32KB of RAM and 512KB of Flash memory, along with 16 10-bit A/D channels and a single 10-bit D/A channel. This microcontroller is based on the ARM7TDMI-STM CPU architecture, which supports real-time emulation and embedded tracing. It integrates 32KB, 64KB, or 512KB of high-speed embedded flash memory. With its 128-bit wide memory interface and unique acceleration structure, it allows 32-bit code to run at maximum clock speeds. For applications where code size needs to be tightly controlled, the 16-bit Thumb mode can reduce code size by over 30% while maintaining minimal performance loss. The small form factor and low power consumption make the LPC2131/2132/2138 highly suitable for small systems like access control devices and point-of-sale (POS) terminals. Its extensive range of serial communication interfaces, combined with on-chip 8/16/32kB SRAM, makes it ideal for communication gateways, protocol converters, soft modems, voice recognition, and low-end imaging applications, providing ample buffer space and robust processing power. Additionally, it includes multiple 32-bit timers, one or two 10-bit 8-channel ADCs, a 10-bit DAC, PWM channels, and up to 47 GPIOs, as well as up to 9 edge or level-triggered external interrupts, making it perfect for industrial control and medical systems. Key Features: ● 16/32-bit ARM7TDMI-S microcontroller in a compact LQFP64 package. ● 8/16/32kB on-chip static RAM. ● Built-in boot loader software supports system/in-application programming (ISP/IAP). Sector erase or full erase takes 400ms, and 256-byte programming takes 1ms. ● Embedded DICE?RT and embedded trace interface for real-time debugging using on-chip RealMonitor software and high-speed trace execution code. ● One (LPC2132/2132) or two (LPC2138) eight 10-bit A/D converters with a total of 16 analog inputs, each channel taking 2.44µs for conversion. ● A 10-bit D/A converter with various analog outputs (LPC2132/2138). ● Two 32-bit timer/counters (each with 4 capture and 4 compare channels), a PWM unit (6 outputs), and a watchdog. ● Real-time clock with an independent power supply and clock source, significantly reducing power consumption in power-saving mode. ● Multiple serial interfaces, including two 16C550 industry-standard UARTs, two high-speed I²C interfaces (400kbit/s), SPI and SSP (buffered with variable data length). ● Vector interrupt controller with privilege and vector addresses configurable. ● Up to 47 5V general-purpose I/O ports (LQFP64 package). ● 9 edge or level-triggered external interrupt pins. ● CPU operating frequency of up to 60MHz via on-chip PLL with a stabilization time of 100µs. ● On-chip crystal frequency range: 1~30MHz. ● Two low-power modes: idle and power-down. ● Power consumption can be optimized by enabling/disabling external functions and lowering the external clock. ● Wake up the processor from power-down mode using an external interrupt. ● Single power supply with power-on reset (POR) and brownout detection (BOD) circuits: - CPU operating voltage range: 3.0~3.6V (3.3V±10%), with I/O ports tolerating a maximum voltage of 5V.
