MAX326CEE+T

MAX326CEE+T is a member of Maxim Integrated’s MAX326xx ultra‑low‑power microcontroller family. It’s a compact 32‑bit MCU (ARM Cortex core) designed for battery‑powered sensing applications—wearables, medical devices, and IoT nodes—where long battery life and fast wakeup matter. It combines a low‑power core with on‑chip analog peripherals (ADC/DAC, op‑amps, comparators), flexible timers, and multiple serial interfaces (SPI, I2C, UART) plus embedded memory. The +T suffix typically indicates a variant with extended temperature/industrial-grade capabilities; exact temperature range and features depend on the specific part, so check the datasheet. Supported by Maxim’s development tools, kits, and example firmware for rapid prototyping and deployment.

Here are the typical features of MAX326CEE+T (family-wide; exact specs vary by device—see datasheet for exact numbers):
- 32-bit ARM Cortex-M4F MCU core (DSP-capable)
- Clock: up to tens of MHz (specific max per device)
- On-chip memory: Flash and RAM (sizes vary by part)
- Rich analog: multiple 12‑bit ADCs, DACs, op-amps, comparators, and temperature sensor
- Peripherals: UART/ USART, I2C, SPI, I2S, USB Full-Speed, PWM, timers, RTC, watchdog
- Security: hardware crypto engine (AES/SHA), secure boot, memory protection features
- Power management: ultra-low-power modes with rapid wakeup; on-chip regulator options and battery monitoring
- Debug/Programming: SWD/JTAG support, on-chip bootloader
- Packaging: compact packages (QFN/LQFP) with extended temperature options
- Robustness: ESD protection and reliability features
Note: exact memory size, clock speed, peripherals count, and temperature range depend on the specific MAX326CEE+T device. Refer to the exact datasheet for precise specs.

- Manufacturer: Maxim Integrated (now part of Analog Devices, Inc.)
- What kind of company: An American multinational semiconductor company that designs and manufactures analog and mixed‑signal integrated circuits.
