Texas Instruments CP3BT26Y98NEP/NOPB

Overview

CP3BT26Y98NEP/NOPB from Texas Instruments is a reprogrammable connectivity processor integrating a 24-MHz CR16C RISC core, 256 KB Flash program memory, 32 KB SRAM, and hardware peripherals including Bluetooth Lower Link Controller (v1.1), USB 1.1 full-speed node, CAN 2.0B interface (1 Mbps), quad UART, 12-bit 8-channel ADC, and CVSD/PCM audio conversion - designed for embedded wireless gateways and industrial handhelds requiring concurrent wired/wireless I/O.

For engineers reviewing the CP3BT26Y98NEP/NOPB datasheet, CP3BT26Y98NEP/NOPB pinout, CP3BT26Y98NEP/NOPB application, or CP3BT26Y98NEP/NOPB equivalent, key selection criteria include its dual-clock reset architecture, 48 GPIO pins in LQFP-128 package, integrated Bluetooth LLC with 4.5 KB dedicated RAM, CAN message buffer configuration, and power management modes supporting Halt/Idle/Power Save states.

Technical Context

The CP3BT26Y98NEP/NOPB implements a pipelined CR16C CPU core capable of one instruction per clock cycle at 24 MHz, with on-chip PLL generating internal clocks from a 12-MHz external crystal. Its triple-clock system includes main, slow, and PLL-derived clocks, enabling precise timing control for Bluetooth hopping (1600 hops/s), CAN bit timing, and USB frame synchronization.

Hardware peripheral integration is memory-mapped and interrupt-driven: the CAN module uses 15 configurable message buffers with dual acceptance filters and time-stamp counter; the Bluetooth LLC provides BlueRF-compatible mode-2/3 interface to TI's LMX5252 transceiver; and the 12-bit ADC supports 4-wire touchscreen with pendown detection and programmable reference selection (ADVCC, VREFP, ADC0–ADC3).

FAQ

What is the maximum operating frequency of the CP3BT26Y98NEP/NOPB CPU core?

The CP3BT26Y98NEP/NOPB features a CR16C RISC core rated for up to 24 MHz operation, delivering a minimum instruction cycle time of 41.7 ns. This frequency is supported by an on-chip PLL that locks to a 12-MHz external crystal, enabling deterministic real-time execution for Bluetooth baseband and CAN protocol handling within the CP3BT26Y98NEP/NOPB.

Does the CP3BT26Y98NEP/NOPB support Bluetooth 2.0 or later specifications?

No, the CP3BT26Y98NEP/NOPB implements Bluetooth Specification Version 1.1 only, as confirmed in its official datasheet (SNOSAE5D). It includes the Lower Link Controller (LLC) with support for all v1.1 packet types and fast frequency hopping at 1600 hops/s, but does not support Enhanced Data Rate (EDR), Secure Simple Pairing (SSP), or Bluetooth Low Energy (BLE) introduced in later versions.

Can the CP3BT26Y98NEP/NOPB operate in low-power modes while maintaining CAN bus wake-up capability?

Yes, the CP3BT26Y98NEP/NOPB supports Halt, Idle, and Power Save modes, and the CAN receiver can trigger wake-up via the Multi-Input Wake-Up (MIWU) module. This allows the device to remain in ultra-low-power state until a valid CAN message arrives - critical for battery-powered diagnostic tools using CP3BT26Y98NEP/NOPB in automotive environments.

What external components are required to implement a complete Bluetooth system with the CP3BT26Y98NEP/NOPB?

A complete Bluetooth system requires the CP3BT26Y98NEP/NOPB paired with a compatible RF transceiver such as TI's LMX5252, which connects via the BlueRF-compatible mode-2/3 interface. Additional components include a 12-MHz crystal for the PLL, decoupling capacitors, and optional external memory if expanded beyond the on-chip 12 MB address space - no external USB PHY or CAN transceiver is needed due to integrated peripherals in the CP3BT26Y98NEP/NOPB.

Is the 12-bit ADC in the CP3BT26Y98NEP/NOPB suitable for 4-wire resistive touchscreen applications?

Yes, the CP3BT26Y98NEP/NOPB's 12-bit ADC is explicitly designed for 4-wire resistive touchscreens, featuring integrated low-ohmic drivers on ADC[3:0], hardware pendown detection, and programmable start delay. Its 11-bit effective accuracy and 15 µs conversion time meet response requirements for handwriting recognition and UI navigation in handheld devices using CP3BT26Y98NEP/NOPB.
