Ferroelectric Random Access Memory (FRAM) is a memory technology that combines the best features of Flash and SRAM. It is non-volatile like Flash, but offers fast and low power writes, write endurance of 10^15 cycles and unmatched flexibility. While new to microcontrollers, FRAM has been used in the industry for over a decade.
The MSP low-power microcontroller portfolio offers 16-bit and 32-bit multiplication modules on select devices. These peripherals can be used while the microcontroller is in low-power modes. Combined with optimized fixed and floating-point math libraries, MSP MCU performance can be increased dramatically.
The MSP low-power, advanced microcontroller portfolio provides embedded security systems that allow our customers to prevent, detect and respond to unintended or malicious behavior, including MCU reverse engineering. These secure microcontroller features include Advanced Encryption Standard (AES) hardware accelerators, IP encapsulation memory protection, anti-tampering, the FRAM advantage, among other features listed below.

The power management module (PMM) manages all functions related to the power supply and its supervision for the device. Its primary functions are first to generate a supply voltage for the core logic, and second, provide several mechanisms
for the supervision and monitoring of both the voltage applied to the device (DVCC) and the voltage generated for the core (VCORE).
The PMM uses an integrated low-dropout voltage regulator (LDO) to produce a secondary core voltage (VCORE) from the primary one applied to the device (DVCC).
In general, VCORE supplies the CPU, memories (flash and RAM), and the digital modules, while DVCC supplies the I/Os and all analog modules (including the oscillators). The VCORE output is maintained using a dedicated voltage reference.
VCORE is programmable up to four steps, to provide only as much power as is needed for the speed that has been selected for the CPU. This enhances power efficiency of the system. The input or primary side of the regulator is referred to as its high side. The output or secondary side is referred to as its low side.

Analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) are complex analog functions that consists of analog and digital components, some types use compensation methods and auto-zero (AZ) mechanisms to eliminate error sources. Modern converters provide automatic range control and other advanced features. A-POOL has none of those complex functions as ready modules; instead, it provides analog and analog-oriented digital elementary functions that can be used to build complex analog functions like DACs, ADCs, and SVMs of different kinds when combined through software.
A transimpedance amplifier (TIA) is a high-performance and low-power amplifier with rail-to-rail output. It has programmable power modes to suit different application needs. MSP430FR231x MCUs support a dedicated low-leakage pad for TIA negative input to reduce system current consumption.
The operational amplifiers (OA) support front-end analog signal conditioning prior to analog-to-digital conversion. The OA is a configurable low-current rail-to-rail operational amplifier. It can be configured as an inverting amplifier or a non-inverting amplifier, or it can be combined with other OA modules to form differential amplifiers. The output slew rate of the OA can be configured for optimized settling time vs power consumption.
