Microchip Introduces PIC18 Microcontroller with High-Speed 12-bit ADC
Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced the four-member PIC18F4523 family, which is Microchip’s first family of high-end 8-bit Flash microcontrollers to include a high-speed 12-bit Analog-to-Digital Converter (ADC) peripheral on-chip. Additionally, this microcontroller family includes nanoWatt Technology features, which provide design engineers with multiple options for effectively managing power consumption and extending battery life. These features eliminate the cost and complexity of interfacing to an external ADC, while providing the precision required for high-speed, high-resolution sensor measurements in applications such as medical, industrial and utility metering.
Sophisticated embedded systems are increasingly requiring advanced sensor measurement with very low power consumption and very little board space. By providing a high-end 8-bit microcontroller with a 12-bit, 13-channel ADC and advanced power management in small 28-, 40- and 44-pin packages, Microchip’s PIC18F4523 family is meeting these market needs.
“The addition of 12-bit ADCs to the PIC18 portfolio offers system designers the ability to employ advanced sensor designs that were previously out of reach without the use of external components,” said Mitch Obolsky, vice president of Microchip’s Advanced Microcontroller Architecture Division. “This saves on overall component costs but, more importantly, the effort involved in implementing complex designs.”
The PIC18F4523 family is well suited for a broad range of applications requiring precision measurement and control, including the following examples: Industrial (data logging, data conditioning); Medical (sensor measurements); Power (utility metering, power conversion, battery chargers); Appliances (sensor measurements).
Additional key features of the PIC18F4523 microcontroller family include:
- 10 MIPS performance
- 32 or 16 Kbytes of Enhanced Flash program memory
- 256 bytes of EEPROM data memory
- Up to 1,536 bytes of RAM
- 2 analog comparators with input multiplexing
- Up to two Capture/Compare/PWM modules
- Master I2C(TM) and SPI communication module
- Enhanced USART module with RS-485, RS-232 and LIN support
- One 8-bit and 3x 16-bit timers
- Internal Oscillator (32 MHz to 31 kHz)
The PIC18F4523 family maintains compatibility with Microchip’s free MPLAB(R) IDE integrated development environment, MPLAB C18 C compiler, MPLAB ICD 2 in-circuit debugger and emulator, and the MPLAB PM3 universal device programmer. In addition, the PICDEM(TM) 2 Plus (part # DM163022) demonstrates the capabilities of the PIC18F4523 family.
