Product details
Overview
CP3BT26Y98ACKX/NOPB from Texas Instruments is a reprogrammable connectivity processor integrating Bluetooth 1.1 Lower Link Controller, USB 1.1 full-speed node, CAN 2.0B interface, CR16C RISC core (24 MHz), 256 KB Flash program memory, and 32 KB SRAM. It serves as a system-on-chip for embedded wireless gateways requiring concurrent wired/wireless protocol bridging in industrial telemetry and portable medical devices.
For engineers reviewing the CP3BT26Y98ACKX/NOPB datasheet, CP3BT26Y98ACKX/NOPB pinout, CP3BT26Y98ACKX/NOPB application, or CP3BT26Y98ACKX/NOPB equivalent, key selection criteria include its dual-clock reset architecture, 15-message-buffer CAN controller with time-stamp counter, integrated CVSD/PCM audio conversion, 8-channel 12-bit ADC with touchscreen support, and LQFP-128 package with 48 I/O pins.
Technical Context
The CP3BT26Y98ACKX/NOPB implements a pipelined CR16C CPU core enabling one-instruction-per-cycle execution at 24 MHz, with on-chip PLL clock generation and triple-clock domain management (main/slow/PLL). Its bus interface unit supports up to 12 MB external memory on 144-pin variants-though this LQFP-128 variant omits external bus signals.
Hardware peripherals are memory-mapped and interrupt-driven: Bluetooth LLC uses dedicated 4.5 KB RAM and 1 KB sequencer RAM; CAN module provides 15 configurable message buffers with dual acceptance masks and automatic remote request handling; USB 1.1 node includes seven endpoint pipes (EP0 + six unidirectional) with integrated transceiver and SIE.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar connectivity processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CP3BT26Y98AWMX/NOPB | Identical silicon; differs only in tape-and-reel packaging (no functional difference). | No change in use case - same LQFP-128 footprint, 48 I/O, and peripheral set. | Select for automated SMT assembly where reel packaging is required. |
| CC2564C from Texas Instruments | Bluetooth 4.0 BR/EDR/LE SoC with ARM Cortex-M0, no CAN or USB; 2.4 GHz RF integrated. | Targets BLE-centric applications without wired fieldbus or host USB connectivity requirements. | Choose when Bluetooth Low Energy compatibility and smaller form factor outweigh need for CAN/USB bridging. |
Compared with CP3BT26Y98ACKX/NOPB, CP3BT26Y98AWMX/NOPB offers identical functionality in tape-and-reel format, while CC2564C trades CAN/USB integration for BLE protocol support and integrated RF - making it unsuitable for legacy CAN-based industrial diagnostics but viable for battery-powered BLE sensors.

FAQ
What Bluetooth version and profiles does CP3BT26Y98ACKX/NOPB support?
The CP3BT26Y98ACKX/NOPB integrates a Bluetooth 1.1 Lower Link Controller with hardware support for all packet types and fast frequency hopping. It does not include an upper-layer stack; however, TI's official Bluetooth protocol stack (including SDP, L2CAP, RFCOMM, and service profiles) is provided separately and validated for use with CP3BT26Y98ACKX/NOPB in development environments like IAR Embedded Workbench.
Does CP3BT26Y98ACKX/NOPB support CAN FD or only classical CAN 2.0B?
CP3BT26Y98ACKX/NOPB supports only Classical CAN 2.0B (ISO 11898-1), with bit rates up to 1 Mbps and 15 configurable message buffers. It does not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. The CAN module complies strictly with the 2003 CAN 2.0B specification as documented in the SNOSAE5D datasheet.
Can CP3BT26Y98ACKX/NOPB operate without external memory?
Yes. CP3BT26Y98ACKX/NOPB contains 256 KB Flash program memory, 8 KB Flash data memory, and 32 KB SRAM - sufficient to host a real-time OS, Bluetooth protocol stack, application firmware, and runtime variables. External memory interface signals are omitted in the LQFP-128 package variant (including CP3BT26Y98ACKX/NOPB), confirming its design for self-contained operation.
What is the role of the CVSD/PCM conversion module in CP3BT26Y98ACKX/NOPB?
The CVSD/PCM conversion module in CP3BT26Y98ACKX/NOPB performs real-time hardware-accelerated bidirectional conversion between Bluetooth-specified CVSD voice data and standard PCM formats (8-bit μ-Law/A-Law or 13–16-bit Linear). This offloads computationally intensive audio processing from the CR16C CPU, enabling low-latency voice transmission in hands-free or headset applications without external codec ICs.
Is CP3BT26Y98ACKX/NOPB pin-compatible with other CP3BT26 variants like CP3BT26G18AWM?
No. CP3BT26Y98ACKX/NOPB (LQFP-128, 48 I/O) and CP3BT26G18AWM (LQFP-128, 54 I/O) share the same package outline but differ in I/O count and signal mapping. The Y98 variant disables external bus signals and reduces I/O count to 48, while the G18 variant enables all 54 I/O pins including external memory interface lines - making them functionally and physically non-interchangeable without PCB redesign.
