MSP430 with FRAM – Future of MCU Memory

18

– FRAM is Universal Memory– Superior Endurance

– Proven data retention to 10 years @ 85°C– Over 100 Trillion write/read cycles– Write Guarantee in case of power loss

– Fast write times (like SRAM)– ~50ns per byte – 1,000x faster than Flash/EEPROM

– Non-Volatile, Reliable– Low Power

– Only 1.5v to write & erase – >10-14v for Flash/EEPROM

– Secure– Fast access times– No charge pump– No perceptible difference in read/write processes

– Radiation Resistance - Terrestrial Soft Error Rate (SER) is below detection limits

– Immune to Magnetic Fields - FRAM does not contain iron

FRAM Applications:– Battery Backed SRAM

Replacement – Digital rights management – Data logging, remote sensing– Low Power Electronics– Energy harvesting

FRAM is Programmed by flip of a Ferro Electric Dipole.

Data is representative of embedded memory performance within device

Unified memory: Another dimension of freedom for software developers

One device supporting multiple options “slide the bar as needed”

Multiple device variants may be required

• Easier, simpler inventory management

• Lower cost of issuance / ownership

• Faster time to market for memory modifications

Data vs. program memorypartitioned as needed

• Use Case Example: MSP430F2274 Vs MSP430FR5739

• Both devices use System clock = 8MHz

• Maximum Speed FRAM = 1.5MBps [100x faster]

• Maximum Speed Flash = 12kBps

FRAM = Ultra-fast Writes

• Use Case Example: MSP430F2274 Vs MSP430FR5739

• Both devices write to NV memory @ 12kBps

• FRAM remains in standby for 99% of the time

• Power savings: >200x of flash

FRAM = Low active write duty cycle

• Use Case Example: MSP430F2274 Vs MSP430FR5739

• Average power FRAM = 720µA @ 1.5Mbps

• Average power Flash = 2200µA @ 12kBps

• 100 times faster in half the power

• Enables more unique energy sources

• FRAM = Non-blocking writes

• CPU is not held

• Interrupts allowed

FRAM = Ultra-low Power

• Use Case Example: EEPROM Vs MSP430FR5739

• Many systems require a backup procedure on power fail

• FRAM IP has built-in circuitry to complete the current 4 word write• Supported by internal FRAM LDO & cap

• In-system backup is an order of magnitude faster with FRAM

FRAM = Increased flexibility

• Use Case Example: MSP430F2274 Vs MSP430FR5739

• FRAM Endurance >= 100 Trillion [10^14]

• Flash Endurance < 100,000 [10^5]

• Comparison: write to a 512 byte memory block @ a speed of 12kBps

• Flash = 6 minutes

• FRAM = 100+ years!
