LPC2138-Power Circuit-Circuit Diagram-华强电子网

[Usage] Single-chip circuit [Performance Parameters] The LPC2131 is equipped with a 32/16-bit ARM7TDMI-STM CPU microcontroller in a compact LQFP64 package. It features 32KB of RAM and 512KB of FLASH memory, along with 16 10-bit A/D channels and a 10-bit D/A channel. This microcontroller is designed to support real-time emulation and embedded tracking, thanks to its 32kB, 64kB, and 512kB of embedded high-speed flash memory. With a 128-bit wide memory interface and a unique acceleration architecture, it allows 32-bit code to run at maximum clock speeds. For applications requiring tight control over code size, the 16-bit Thumb? mode can reduce code size by more than 30% with minimal performance loss. The LPC2131's small form factor and low power consumption make it ideal for small systems like access control devices and point-of-sale (POS) machines. Its extensive array of serial communication interfaces and on-chip 8/16/32kB SRAM makes it suitable for communication gateways, protocol converters, soft modems, voice recognition, and low-end imaging applications, offering ample buffer space and powerful processing capabilities. It also includes multiple 32-bit timers, one or two 10-bit 8-channel ADCs, 10-bit DACs, PWM channels, and up to 47 GPIOs, along with 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. ● On-chip static RAM options: 8/16/32kB. ● On-chip boot loader software supports system/in-application programming (ISP/IAP). Sector erase or full erase takes 400ms, while 256 bytes can be programmed in 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) 10-bit 8-channel ADCs with a total of 16 analog inputs, each channel converting in 2.44us. ● One 10-bit D/A converter with varying analog outputs (LPC2132/2138). ● Two 32-bit timer/counters (with 4 capture and 4 compare channels), a PWM unit (6 outputs), and a watchdog. ● Real-time clock with independent power supply and clock source, reducing power consumption in power-saving mode. ● Multiple serial interfaces, including two 16C550 industry-standard UARTs, two high-speed I2C interfaces (400kbit/s), SPI TM and SSP (with buffering and variable data length). ● Vector interrupt controller with privilege and vector addresses configurable. ● Up to 47 5V general-purpose I/O ports (LQFP64 package). ● Nine edge or level-triggered external interrupt pins. ● CPU operating frequency up to 60MHz, achieved via on-chip PLL, with a stabilization time of 100us. ● 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 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 capable of withstanding a maximum voltage of 5V.
