Product Overview: ATMEGA32L-8MUR

The ATMEGA32L-8MUR from Microchip Technology is a high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller. This versatile piece of technology combines 32KB ISP flash memory with read-while-write capabilities, 1KB EEPROM, 2KB SRAM, 32 general purpose I/O lines, 32 general purpose working registers, a real-time counter, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, a 6-channel 10-bit A/D converter (eight channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes.

The device operates at a frequency of up to 16MHz and can work at voltages as low as 2.7V. The ATMEGA32L-8MUR is particularly suitable for battery-powered applications, thanks to its low power consumption. It features an advanced RISC architecture that enables the microcontroller to execute powerful instructions in a single clock cycle, thus achieving throughputs approaching 1 MIPS per MHz and balancing power consumption and processing speed.

Key Features:

• 32KB of in-system self-programmable flash program memory
• 1KB EEPROM and 2KB internal SRAM
• Up to 16 MIPS throughput at 16MHz
• JTAG (Joint Test Action Group) interface for on-chip-debug
• Up to 32 programmable I/O lines
• Eight-channel 10-bit A/D converter
• Power-on reset and programmable brown-out detection
• Internal calibrated RC oscillator for reliable operation
• Innovative QTouch® library for implementing capacitive touch buttons, sliders, and wheels
• Five power-saving modes to reduce power consumption

The ATMEGA32L-8MUR is packaged in a 44-lead thin quad flat pack (TQFP) and is also available in 44-pad QFN/MLF, which is suitable for space-constrained applications. Its robust feature set and power efficiency make it an ideal choice for a wide range of applications, including industrial control, medical systems, access control, point-of-sale, and many more.
