Product details

What this 16-bit DSP brings to a motor-control board

It carries 16 KB of on-chip Flash program memory and 1K x 8 of RAM.

What the 16 KB Flash and 1K RAM mean for firmware

Connectivity and I/O for the control board

With 32 general-purpose I/O lines, CANbus, SCI, SPI, and UART/USART, this DSP can talk to encoder interfaces, HMI panels, and higher-level PLCs over a fieldbus network. The CAN 2.0B controller is particularly useful for distributed drive systems where multiple axes share a common bus. The 8-channel 10-bit ADC samples at rates sufficient for current sensing in a single-motor drive, but not for multi-channel simultaneous sampling or high-bandwidth power conversion.

Frequently asked questions

What is the closest pin-compatible alternative to TMS320F243PGEA?

There is no direct pin-compatible drop-in replacement from TI's current C2000 family. Newer C2000 devices use different packages, supply voltages, and pinouts, so a board redesign is necessary for a production-grade replacement.

What is the TMS320F243PGEA's core speed?

The core runs at 20 MHz, giving a 50 ns instruction cycle for real-time control loops.

What series does the TMS320F243PGEA belong to?

It is part of the C2000 C24x 16-Bit DSP series from Texas Instruments.

Where can I buy the TMS320F243PGEA?
