FRAM
The FRAM can be programmed via the JTAG port, Spy-Bi-Wire (SBW), the BSL, or in-system by the CPU.
Features of the FRAM include:
Low power, ultra fast write non-volatile memory.
Byte and word access capability.
Programmable and automated wait state generation.
Error Correction Coding (ECC) with single bit detection and correction, double bit detection.
Memory Protection Unit (MPU)
The FRAM can be protected from inadvertent CPU execution or write access by the MPU. Features of the MPU
include:
Main memory partitioning programmable up to three segments.
Each segment
's (main and information memory) access rights can be individually selected.
Access violation flags with interrupt capability for easy servicing of access violations.
Peripherals
Peripherals are connected to the CPU through data, address, and control buses and can be handled using all
instructions. For complete module descriptions, see the MSP430FR57xx Family User
's Guide, literature number
Digital I/O
There are up to four 8-bit I/O ports implemented:
All individual I/O bits are independently programmable.
Any combination of input, output, and interrupt conditions is possible.
Programmable pullup or pulldown on all ports.
Edge-selectable interrupt and LPM3.5 and LPM4.5 wake up input capability is available for all ports.
Read/write access to port-control registers is supported by all instructions.
Ports can be accessed byte-wise or word-wise in pairs.
Oscillator and Clock System (CS)
The clock system includes support for a 32 kHz watch crystal oscillator XT1 (LF mode), an internal
very-low-power low-frequency oscillator (VLO), an integrated internal digitally-controlled oscillator (DCO), and a
high-frequency crystal oscillator XT1 (HF mode). The clock system module is designed to meet the requirements
of both low system cost and low-power consumption. A fail-safe mechanism exists for all crystal sources. The
clock system module provides the following clock signals:
Auxiliary clock (ACLK), sourced from a 32 kHz watch crystal (XT1 LF mode), a high-frequency crystal (XT1
HF mode), the internal low-frequency oscillator (VLO), or the internal digitally-controlled oscillator DCO.
Main clock (MCLK), the system clock used by the CPU. MCLK can be sourced by same sources made
available to ACLK.
Sub-Main clock (SMCLK), the subsystem clock used by the peripheral modules. SMCLK can be sourced by
same sources made available to ACLK.
Power Management Module (PMM)
The PMM includes an integrated voltage regulator that supplies the core voltage to the device . The PMM also
includes supply voltage supervisor (SVS), as well as brownout protection. The brownout circuit is implemented to
provide the proper internal reset signal to the device during power-on and power-off. The SVS circuitry detects if
the supply voltage drops a safe level and below a user-selectable supports both supply voltage supervision. SVS
circuitry is available on the primary and core supplies.
