Product details

What this MSP430F5659IZCAT brings to a BOM

The 74 general-purpose I/O lines, combined with I²C, SPI, UART, and IrDA serial interfaces, give this MCU the peripheral mix for a multi-sensor data concentrator or a human-machine interface panel.

Package and rework — the NFBGA reality

This part comes in a 113-ball NFBGA package, 7x7 mm body. Rework requires a reflow station with preheat plate and stencil. For prototype or low-volume builds, the cut-tape option lets you buy a few pieces without committing to a full reel. The tape-and-reel variant is the standard production feed for pick-and-place lines.

Memory and data converter resources

The 512 KB Flash is large for a 16-bit ultra-low-power MCU — enough to hold a full protocol stack (USB, TCP/IP offload) plus application code without external memory. The 66 KB RAM supports moderate-sized data buffers and real-time operating system heaps. The integrated 12-bit ADC has 16 channels, and there are two 12-bit DAC outputs, covering analog front-end needs for most industrial sensor interfaces without external converters.

Frequently asked questions

Does MSP430F5659IZCAT have USB connectivity?

Yes, the MSP430F5659IZCAT includes a full-speed USB 2.0 interface integrated on-chip. It supports device-mode operation and can be used for USB-to-serial bridges, data logging to a host PC, or firmware updates over USB.

What is the pinout of MSP430F5659IZCAT?

The pinout is defined by the 113-ball NFBGA (7x7 mm) package. Pin 1 is located at the corner marked by a chamfer on the package body. The full ball-map is documented in the MSP430F5659 device-specific datasheet from Texas Instruments.

What is the closest pin-compatible alternative to MSP430F5659IZCAT?

Within the MSP430F5xx family, the MSP430F5658 and MSP430F5657 are pin-compatible 113-NFBGA variants with the same peripheral set but smaller Flash (384 KB and 256 KB respectively). Check the specific memory requirements before substituting — the pinout is identical, but the firmware image must fit the smaller Flash.

Is MSP430F5659IZCAT RoHS compliant?

Yes, the MSP430F5659IZCAT is RoHS-compliant. The package is lead-free and compatible with standard lead-free reflow profiles used in production assembly.
