STMicroelectronics STEVAL-CBP006V1

Overview

STEVAL-CBP006V1 from STMicroelectronics is a UniPower demonstration board centered on the STM8S105C microcontroller (LQFP48), delivering integrated standby power management and capacitive touch-sensing user interface control for set-top boxes, digital TVs, and consumer appliances. It features a 5 A PMOS power switch, 6 mechanical switches, 4 touch buttons + 1 slider, 4-digit 7-segment display, 6 controllable LEDs, ambient light sensing, and 36 kHz IR receiver.

For engineers reviewing the STEVAL-CBP006V1 datasheet, STEVAL-CBP006V1 pinout, STEVAL-CBP006V1 application, or STEVAL-CBP006V1 equivalent, this board serves as a ready-to-evaluate platform for low-standby-power system wake-up control, capacitive touch integration, I²C host interfacing, and firmware customization via SWIM debug interface - all with preloaded demonstration firmware and full MCU I/O accessibility.

Technical Context

The board implements dual-role power management: permanent 3.3 V/5 V rails sustain MCU and peripherals in standby, while APP_PWR is switched on-demand via the STM8S105C-controlled PMOS. Wake-up sources include mechanical switches, touch sensors, IR remote, and external interrupt signals routed to dedicated host interface pins.

Capacitive touch functionality uses ST's hardware-accelerated charge-transfer method on PB1–PB4 and PB6–PB7, supported by the UniPower firmware library; analog inputs (PA1–PA6, PB0–PB7, PC1–PC7, PD0–PD7, PE0–PE7, PG0–PG1) enable flexible sensor and control expansion. All I/Os are exposed on P2 (50-pin header) and CN1/CN3 for debugging and host integration.

FAQ

What firmware is preloaded on the STEVAL-CBP006V1?

The board ships with demonstration firmware that manages all onboard hardware: mechanical/touch inputs, 7-segment display, LEDs, IR reception, ambient light dimming, and APP_PWR switching. Firmware supports immediate evaluation without programming and is adaptable via SWIM interface using ST Visual Develop or STVD.

Can the STM8S105C be replaced with another MCU in the same footprint?

Yes - the board supports alternative MCU placement in VFQFN32 package within the LQFP48 footprint, enabling migration to smaller-footprint STM8S variants (e.g., STM8S103F) where reduced peripheral count or memory size suffices for target applications.

Does the board support I²C communication with a host processor?

Yes - CN4 provides dedicated I²C_SDA and I²C_SCL signals (mapped to PE2 and PE1), along with interrupt, reset, and wakeup outputs, enabling seamless bidirectional control and status reporting between the UniPower board and host SoC or MCU.

Is touch-sensing performance affected by PCB layout or overlay material?

Yes - capacitive touch accuracy depends on trace geometry, ground plane integrity, overlay thickness (≤3 mm recommended), and dielectric constant. ST's AN3239 and UM0907 provide validated layout rules and tuning guidelines specific to this board's PBx-based sensor routing.
