LPC2131-Power Circuit-Circuit Diagram-华强电子网

[Usage] Single-chip circuit

[Performance Parameters]

Available in a compact LQFP64 package. Features 8KB of RAM, 32KB of FLASH, and 8 10-bit A/D channels.

The LPC2131 is built around a 32/16-bit ARM7TDMI-STM CPU microcontroller with support for real-time emulation and embedded tracing. It includes 32kB, 64kB, or 512kB of embedded high-speed flash memory. The 128-bit wide memory interface and unique acceleration architecture allow 32-bit code to run at maximum clock speeds. For applications needing tight control over code size, the 16-bit Thumb? mode can reduce code size by over 30% with minimal performance loss.

The small form factor and low power consumption make the LPC2131/2132/2138 ideal for small systems like access control and point-of-sale (POS) devices. A wide range of serial communication interfaces and on-chip 8/16/32kB SRAM make the LPC2131/2132/2138 suitable for communication gateways, protocol converters, soft modems, voice recognition, and low-end imaging, offering extensive buffer space and powerful processing capabilities. Multiple 32-bit timers, 1 or 2 10-bit 8-channel ADCs, 10-bit DACs, PWM channels, and 47 GPIOs, along with up to 9 edge or level-triggered external interrupts, make them ideal for industrial control and medical systems.

Characteristics:

● 16/32-bit ARM7TDMI-S microcontroller in a compact LQFP64 package.

● 8/16/32kB on-chip static RAM.

● On-chip boot loader software supports system/in-application programming (ISP/IAP). Sector erase or full erase takes 400ms, with 1ms programmability for 256-byte blocks.

● 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 containing a total of 16 analog inputs with a conversion time of 2.44μs per channel.

● One 10-bit D/A converter with different analog outputs (LPC2132/2138).

● Two 32-bit timer/counters (with 4 capture and 4 compare channels), PWM unit (6 outputs), and watchdog.

● Real-time clock with 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 (400 kbit/s), SPI and SSP (with buffering and variable data length).

● Vector interrupt controller with configurable privilege and vector addresses.

● 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 PLL stabilization time of 100μs.

● On-chip crystal frequency range: 1~30 MHz.

● Two low-power modes: idle and power-down.

● Power consumption can be optimized by enabling/disabling external functions and reducing 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: 3.0~3.6 V (3.3 V±10%), with I/O ports able to withstand a maximum voltage of 5V.
