Infineon Technologies CY8C6036BZI-F04

Overview

CY8C6036BZI-F04 from Infineon is a PSOC™ 61 MCU featuring a 150-MHz Arm® Cortex®-M4F CPU with floating-point unit and MPU, 1-MB flash, 288-KB SRAM, integrated CAPSENSE™, and dual-core architecture (M4 + reserved M0+). It operates from 1.7 V to 3.6 V, supports Deep Sleep at 7 µA with 64-KB SRAM retention, and integrates SIMO DC-DC converter (<1 µA quiescent current). Used in battery-powered IoT edge nodes requiring secure, low-power sensor fusion and capacitive touch.

For engineers reviewing the CY8C6036BZI-F04 datasheet, CY8C6036BZI-F04 pinout, CY8C6036BZI-F04 application, or CY8C6036BZI-F04 equivalent, key selection criteria include dual-CPU power efficiency (22 µA/MHz @ 0.9 V core), on-chip cryptographic acceleration (AES/SHA/TRNG), QSPI XIP support up to 640 Mbps, and CAPSENSE™ liquid-tolerant proximity sensing capability.

Technical Context

The CY8C6036BZI-F04 implements a tightly coupled dual-CPU subsystem where the Cortex-M4F handles application execution while the Cortex-M0+ is dedicated to system-level services (e.g., BLE stack, security monitor) and not user-accessible. Clocking uses a hierarchical tree with FLL (IMO-based), PLL (external crystal-based), and fractional dividers enabling precise peripheral clock tuning.

Analog subsystem integration includes a 12-bit 1-Msps SAR ADC with 16-channel sequencer and hardware averaging, two Deep Sleep-capable comparators, a 12-bit DAC with <2-µs settling time, and two opamps with configurable low-power modes - all accessible via programmable routing to up to 100 GPIOs including six overvoltage-tolerant pins.

Key Specifications

Pinout & Package

The CY8C6036BZI-F04 is housed in a 124-ball BGA package (6 × 6 mm, 0.5 mm pitch) with 100 usable GPIOs, including six overvoltage-tolerant (OVT) pins and two Smart I/O ports (16 pins total) supporting Boolean logic during Deep Sleep.

FAQ

What is the maximum operating frequency of the Cortex-M4F core in CY8C6036BZI-F04?

The Cortex-M4F core operates at up to 150 MHz, verified under 1.1-V core voltage conditions per Infineon's 002-21414 Rev. *R datasheet. At 0.9-V core, maximum frequency is reduced to maintain timing closure and power efficiency, with active current slope specified at 22 µA/MHz.

Does CY8C6036BZI-F04 support external memory execution (XIP)?

Yes - it supports Execute-In-Place from external quad SPI flash via its QSPI/SMIF interface, with on-the-fly AES-128 decryption and a dedicated 4-KB cache to reduce latency and power consumption during code fetch operations.

Can the Cortex-M0+ core be used for application code development?

No - in the CY8C6036BZI-F04 (PSOC™ 61 series), the Cortex-M0+ is reserved exclusively for system functions including BLE stack handling, security monitoring, and inter-processor communication; it is not accessible to user application firmware.

What is the role of the SIMO DC-DC converter in this MCU?

The on-chip Single-In Multiple-Out (SIMO) buck converter delivers regulated voltages to multiple internal domains (CPU, analog, I/O) with <1 µA quiescent current, enabling efficient power conversion from a single input supply and eliminating need for external PMIC in space-constrained designs.
