Engineering Selection Recommendations

The PIC16F690-E/SS is qualified as a direct substitute for the PIC16C717-E/SS based on the following engineering criteria:

Electrical Compatibility: Both devices operate at identical core voltage (4V ~ 5.5V overlap), clock speed (20MHz), and temperature range (-40°C ~ 125°C). The PIC16F690-E/SS extends the lower voltage limit to 2V, providing additional operational flexibility without compromising the original specification envelope.

Mechanical Compatibility: Identical 20-SSOP surface mount package with matching pin count and physical dimensions (0.209", 5.30mm width) ensures direct PCB footprint compatibility.

Regulatory Compliance: Both devices maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, satisfying identical regulatory requirements.

Functional Enhancement: The PIC16F690-E/SS provides superset capabilities including FLASH reprogrammability (versus OTP), doubled program memory (7KB versus 4.6KB), additional I/O pins (18 versus 15), enhanced analog conversion (12x10b versus 6x10b), and UART/USART connectivity. These enhancements do not introduce incompatibility; they expand available functionality within the same physical and electrical constraints.

Product Status: Both devices maintain active product status with verified programmability through DiGi-Electronics.

Frequently Asked Questions (FAQ)

Q: Can the PIC16F690-E/SS replace the PIC16C717-E/SS in existing designs?

A: Yes. Both devices share identical core processor architecture, clock speed, package form factor, and operating temperature range. The PIC16F690-E/SS provides superset functionality without introducing electrical or mechanical incompatibility.

Q: What is the primary difference between these devices?

A: The main difference is program memory type: PIC16C717-E/SS uses OTP (one-time programmable), while PIC16F690-E/SS uses FLASH (reprogrammable). The PIC16F690-E/SS also provides doubled program memory capacity, additional I/O pins, enhanced analog conversion, and extended voltage range.

Q: Are the pin assignments identical?

A: Both devices use the 20-SSOP package with matching physical dimensions. Pin compatibility must be verified against the specific application schematic, as the PIC16F690-E/SS provides additional I/O pins (18 versus 15) that may require design consideration.

Q: Does the voltage supply range difference affect compatibility?

A: No. The PIC16F690-E/SS extends the lower voltage limit to 2V, while maintaining the 4V ~ 5.5V range of the original device. Systems designed for 4V ~ 5.5V operation remain fully compatible.

Q: Are both devices RoHS compliant?

A: Yes. Both the PIC16C717-E/SS and PIC16F690-E/SS are ROHS3 compliant with REACH unaffected status and EAR99 export classification.

Q: What is the inventory status for these parts?

A: PIC16C717-E/SS: 1006 Pcs new original in stock. PIC16F690-E/SS: 20200 Pcs new original in stock.
