FAQ
What is the maximum operating frequency of the MSP430FR6989IPZ?
The MSP430FR6989IPZ operates at up to 16 MHz using its factory-trimmed DCO or external HFXT crystal. This frequency is fully supported across all voltage ranges (1.8 V to 3.6 V), and timing specifications-including ADC conversion and FRAM access-are guaranteed at this speed per the SLAS789D datasheet revision August 2018.
Does the MSP430FR6989IPZ support hardware AES encryption?
Yes, the MSP430FR6989IPZ integrates a dedicated AES256 security coprocessor capable of both encryption and decryption. It supports 128-bit and 256-bit keys, includes a true random number seed generator, and operates independently of the CPU-enabling secure firmware updates and encrypted data logging without performance penalty.
How many I/O pins does the MSP430FR6989IPZ provide, and which ports support capacitive touch?
The MSP430FR6989IPZ provides 83 programmable I/O pins in its 100-pin LQFP package. All pins across ports P1 through P10 and PJ support capacitive touch sensing natively-requiring no external components-via the integrated CapTIvate™-compatible peripheral logic documented in the device user's guide.
What LCD segment count does the MSP430FR6989IPZ support, and what mux configurations are available?
The MSP430FR6989IPZ integrates the LCD_C module supporting up to 320 segments in static, 2-, 3-, 4-, 6-, or 8-mux configurations. Segment drive capability is distributed across P1–P10 and PJ pins, with COM outputs on P6 and P2; configuration is software-defined and compatible with common glass LCD modules used in utility meters.
Is the Extended Scan Interface (ESI) on the MSP430FR6989IPZ usable for gas volume measurement?
Yes-the ESI peripheral in the MSP430FR6989IPZ is explicitly qualified for gas volume measurement per TI's application documentation and reference designs. It performs high-resolution, low-noise background scanning of resistive/capacitive sensor arrays (e.g., thermal mass flow sensors), eliminating need for external amplifiers or ADCs while maintaining sub-µA active current.
