Product details
Overview
CP3BT26Y98NEPX/NOPB from Texas Instruments is a reprogrammable connectivity processor integrating Bluetooth 1.1 LLC, USB 1.1 full-speed node, CAN 2.0B interface, CR16C RISC core (24 MHz), 256 KB Flash program memory, and 32 KB SRAM - designed for embedded wireless gateways requiring concurrent wired/wireless protocol bridging in industrial telemetry systems.
For engineers reviewing the CP3BT26Y98NEPX/NOPB datasheet, CP3BT26Y98NEPX/NOPB pinout, CP3BT26Y98NEPX/NOPB application, or CP3BT26Y98NEPX/NOPB equivalent, key selection criteria include Bluetooth baseband hardware offload, dual-clock reset architecture, 15-message-buffer CAN controller with time stamp counter, and MIWU-enabled wake-up from Halt/Idle/Power Save modes via CAN, UART, or ACB peripherals.
Technical Context
The CP3BT26Y98NEPX/NOPB implements a pipelined CR16C CPU core enabling one-instruction-per-cycle execution at up to 24 MHz, with on-chip PLL clock generation and dual-clock/reset architecture supporting independent main/slow/PLL domains. Its bus interface unit (BIU) manages memory-mapped access to 256 KB Flash, 8 KB Flash data, and 32 KB SRAM while supporting external memory expansion on 144-pin variants - though CP3BT26Y98NEPX/NOPB uses LQFP-128 packaging and excludes external bus capability.
Hardware peripheral integration includes a Bluetooth Lower Link Controller with 4.5 KB dedicated RAM and 1 KB Sequencer RAM, a full-speed USB 1.1 node with seven endpoint pipes (including control EP0), and a CAN 2.0B module with 15 configurable message buffers, dual acceptance masks, priority decoder, and 16-bit time stamp counter - all accessible via memory-mapped registers and interruptible through 47 maskable ICU vectors plus NMI.

Equivalent & Alternatives
The following parts are listed as comparable options for similar reprogrammable connectivity processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CP2102N-A02-GQFN24 | USB-to-UART bridge only; no Bluetooth, CAN, or MCU core - lacks protocol processing capability | Suitable only for simple serial tunneling; cannot replace CP3BT26Y98NEPX/NOPB in multi-protocol gateway roles | Select only when USB-to-serial conversion is sole requirement and Bluetooth/CAN integration is handled externally |

FAQ
What Bluetooth specification version does CP3BT26Y98NEPX/NOPB implement?
CP3BT26Y98NEPX/NOPB implements Bluetooth Specification Version 1.1, including full Lower Link Controller (LLC) functionality with support for all packet types, fast frequency hopping at 1600 hops/second, and BlueRF-compatible interface for pairing with TI's LMX5252 RF transceiver. It does not support Bluetooth 2.0+ EDR, 4.x, or 5.x features.
Does CP3BT26Y98NEPX/NOPB support external memory expansion?
No, CP3BT26Y98NEPX/NOPB in LQFP-128 package does not support external memory expansion. External bus capability is reserved for LQFP-144 variants (e.g., CP3BT26G18AWMX). The CP3BT26Y98NEPX/NOPB provides 256 KB Flash, 8 KB Flash data, and 32 KB SRAM entirely on-die - sufficient for Bluetooth stack, RTOS, and application firmware in most embedded gateway designs.
What is the maximum operating frequency of the CR16C core in CP3BT26Y98NEPX/NOPB?
The CR16C CPU core in CP3BT26Y98NEPX/NOPB operates at a maximum frequency of 24 MHz, achieving a minimum instruction cycle time of 41.7 ns. This frequency is derived from the internal PLL locked to a 12 MHz external crystal, and the core remains fully static - permitting operation down to 0 Hz in Halt mode without data loss.
How many CAN message buffers does CP3BT26Y98NEPX/NOPB provide, and what is their configuration flexibility?
CP3BT26Y98NEPX/NOPB provides 15 memory-mapped CAN message buffers, each individually configurable as transmit or receive. Two independent acceptance filters - one for buffers 0–13 and another for buffer 14 - allow selective message routing. A priority decoder enables dynamic assignment of transmit priority, and the 16-bit time stamp counter supports real-time synchronization in distributed control networks.
Is CP3BT26Y98NEPX/NOPB pin-compatible with other CP3BT26 variants such as CP3BT26G18AWM/NOPB?
Yes, CP3BT26Y98NEPX/NOPB is pin-compatible with CP3BT26G18AWM/NOPB and other LQFP-128 CP3BT26 variants. All share identical pin assignments, electrical characteristics, and thermal pad layout per TI's SNOSAE5D datasheet. Differences are limited to internal Flash configuration (e.g., NSID field) and temperature screening - not affecting PCB design or interconnect.
