MSP430F2131IRGER Key Features

• 16-bit core ?C provides efficient integer math and predictable timing for control loops and protocol stacks.
• Ultra-low power modes ?C reduce battery drain in sleep and standby compared with typical 8-bit options.
• Integrated analog ?C 10-bit ADC and comparator simplify sensor interface and reduce external component count.
• Compact package ?C 20-pin TSSOP saves board area versus larger 28?C40 pin MCUs while keeping multiple I/O lines.

Typical Applications

• Battery-powered sensors and data loggers where low standby current and compact packaging enable multi-year battery life and smaller enclosures.
• Portable medical and measurement modules needing a 16-bit CPU for precise timing and a 10-bit ADC for analog signal acquisition with minimal external parts.
• Industrial control nodes that require reliable temperature range (-40 ??C to 85 ??C) and deterministic timers for motor control or timed sequencing.
• Consumer products and remote controls where cost, size and low-power sleep modes reduce BOM and extend usable life between battery changes.

MSP430F2131IRGER Advantages vs Typical Alternatives

This device combines a 16-bit CPU and integrated analog peripherals in a smaller 20-pin package. Compared with common 8-bit microcontrollers, it offers higher computational efficiency and more precise timing for control tasks. Versus larger MCUs, it costs less and consumes less energy while still providing useful RAM and Flash sizes. The 1.8?C3.6 V supply range and wide temperature support make it practical across more designs without heavy power-management overhead.

FAQ

What development tools are available?

Use TI??s Code Composer Studio or IAR Embedded Workbench for C/C++ development. Both toolchains support device programming, debugging and emulation for MSP430 devices, helping engineers reduce time to prototype.

How is power consumption managed?

The family provides multiple low-power modes and fast wake-up timing. Designers can minimize sleep current and selectively enable peripherals to optimize average power for battery-operated systems.

Which package and pin count apply?

The device is offered in a 20-pin TSSOP package (suffix RGE). This compact footprint balances I/O availability and board area for constrained designs while remaining industry-standard for automated assembly.

Is the ADC suitable for sensor inputs?

The on-chip 10-bit ADC supports typical sensor ranges and avoids many external components. For higher resolution tasks, system designers may add an external ADC but can rely on the integrated ADC for many measurements.

What temperature range does it support?

Designed for industrial environments, the device supports a -40 ??C to 85 ??C ambient range, making it suitable for outdoor and factory-floor applications without special thermal controls.
