Lpc2148

LPC2148 I2C I2C (Inter Integrated Circuit) is a serial interface that uses only 2 wires for low speed communication between I2C devices like Magnetometer, Gyroscope, RTC etc.

How many pins are there in LPC2148?

LPC2148 has two 32-bit General Purpose I/O ports. Out of these 32 pins, 28 pins can be configured as either general purpose input or output.

Why is LPC 2148 used?

RAM Memory System: LPC2148 provides 32kB of static RAM which may be used for code and/or data storage. It may be accessed as 8-bit, 16-bit and 32-bits.

What is UART in LPC2148?

UART (Universal Asynchronous Receiver/Transmitter) is a serial communication protocol in which data is transferred serially bit by bit at a time. Asynchronous serial communication is widely used for byte oriented transmission. In Asynchronous serial communication, a byte of data is transferred at a time.

What are features of LPC2148?

LPC2148 Key Features:

16/32-bit ARM7TDMI Microcontroller in a tiny LQFP64 package.
40 kB of on-chip static RAM and 512 kB of on-chip flash memory.
In-System Programming/In-Application Programming (ISP/IAP) via on-chip boot loader software. ...
USB 2.0 full-speed compliant device controller with 2 kB of endpoint RAM.

What is LPC2148 microcontroller?

The NXP (founded by Philips) LPC2148 is an ARM7TDMI-S based high-performance 32-bit RISC Microcontroller with Thumb extensions 512KB on-chip Flash ROM with In-System Programming (ISP) and In-Application Programming (IAP), 32KB RAM, Vectored Interrupt Controller, Two 10bit ADCs with 14 channels, USB 2.0 Full Speed

What size is LPC2148?

The LPC2148 microcontrollers are based on a 32/16 bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combines the microcontroller with embedded high-speed flash memory ranging from 32 kB to 512 kB.

What is LPC in ARM?

LPC is a family of 32-bit microcontroller integrated circuits by NXP Semiconductors (formerly Philips Semiconductors). The LPC chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0.

What is ADC in LPC2148?

Analog to Digital Converter(ADC) is used to convert analog signal into digital form. LPC2148 has two inbuilt 10-bit ADC i.e. ADC0 & ADC1. ADC0 has 6 channels &ADC1 has 8 channels. Hence, we can connect 6 distinct types of input analog signals to ADC0 and 8 distinct types of input analog signals to ADC1.

What is PWM in LPC2148?

The PWM in LPC2148 is based on standard 32-bit Timer Counter, i.e. PWMTC (PWM Timer Counter). This Timer Counter counts the cycles of peripheral clock (PCLK). Also, we can scale this timer clock counts using 32-bit PWM Prescale Register (PWMPR). LPC2148 has 7 PWM match registers (PWMMR0 – PWMMR06).

Where is ARM7 used?

Arm processors are used extensively in consumer electronic devices such as smartphones, tablets, wearables and other mobile devices. They're also used in a wide range of sensors and internet of things devices.

What is RTC in LPC2148?

LPC2148 has an inbuilt RTC. LPC2148RTC can be clocked by a separate 32.768 KHz oscillator or by a programmable prescale divider based on the APB clock. It maintains a calendar and clock and provides seconds, minutes, hours, month, year, day of week, day of month and day of year.

What is baud rate?

The baud rate is the rate at which information is transferred in a communication channel. Baud rate is commonly used when discussing electronics that use serial communication. In the serial port context, "9600 baud" means that the serial port is capable of transferring a maximum of 9600 bits per second.

What is SPI LPC2148?

Introduction. The Serial Peripheral Interface (SPI) is a bus interface connection protocol originally started by Motorola Corp. SPI Interface uses four wires for communication. Hence it is also known as four wire serial communication protocol. SPI is a full duplex master-slave communication protocol.

Is ARM7 and LPC2148 same?

LPC2148 is a 16-bit or 32-bit microcontroller based on ARM7 family.

What IDE does LPC2148 support?

Which IDE is supported by LPC2148 board? Explanation: Using Real view compiler the keil uVersion 4 is used.

What does ARM stand for?

ARM stands for Advanced RISC Machine. ARM architectures represent a different approach to how the hardware for a system is designed when compared to more familiar server architectures like x86.

CAN protocol in LPC2148?

CAN bus is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer. The CAN communication protocol is a CSMA/CD protocol.

Is ARM and ARM7 same?

The two are quite different, though they can share code, if the code is written for this. Arm Cortex-M0 uses the Armv6-M (only supports 16-bit thumb instructions). Arm Cortex-M3 and later uses the Armv7-M which supports the Thumb2 instruction set (16-bit + 32-bit instructions).

Is ARM a processor or controller?

Basically ARM is a 16 bit/ 32 bit Processors or Controllers. ARM is the heart of advanced digital products like mobile phones automotive systems digital cameras and home networking and wireless technologies.
