CYT2B6 has four major subsystems: CPU, system resources, peripherals, and I/O[4, 5]. The color-coding shows the lowest power mode where the particular block is still functional. The JTAG interface is fully compatible with industry-standard third-party probes such as I-jet, J-Link, and GHS. CYT2B6 provides extensive support for programming, testing, debugging, and tracing of both hardware and firmware. Additionally, each device interface can be permanently disabled for applications concerned with phishing attacks from a maliciously reprogrammed device or attempts to defeat security by starting and interrupting flash programming sequences. All programming, debug, and test interfaces are disabled when maximum device security is enabled. Debug-on-chip functionality enables in-system debugging using the production device. It does not require special interfaces, debugging pods, simulators, or emulators. The debug circuits are enabled by default. CYT2B6 provides a high level of security with robust flash protection and the ability to disable features such as debug. Notes 4. GPIO_STD supporting 2.7 V to 5.5 V VDDIO range. 5. GPIO_ENH supporting 2.7 V to 5.5 V VDDIO range with higher currents at lower voltages. Document Number: 002-25756 Rev. *B Page 6 of 139 CYT2B6 Datasheet 3. Functional Description 3.1 CPU Subsystem 3.1.1 CPU The CYT2B6 CPU subsystem contains a 32-bit Arm Cortex-M0+ CPU with MPU and a 32-bit Arm Cortex-M4F CPU with MPU, and single-precision FPU. This subsystem also includes P-/M-DMA controllers, a cryptographic accelerator, 576 KB of code-flash, 64 KB of work-flash, 64 KB of SRAM, and 32 KB of ROM. The Cortex-M0+ CPU provides a secure, un-interruptible boot function. This guarantees that, following completion of the boot function, system integrity is valid and privileges are enforced. Shared resources (flash, SRAM, peripherals, and so on) can be accessed through bus arbitration, and exclusive accesses are supported by an inter-processor communication (IPC) mechanism using hardware semaphores. 3.1.2 DMA Controllers CYT2B6 has three DMA controllers: P-DMA0 with 16 general-purpose and 38 dedicated channels, P-DMA1 with 8 general-purpose and 18 dedicated channels, and M-DMA0 with two channels. P-DMA is used for peripheral-to-memory and memory-to-peripheral data transfers and provides low latency for a large number of channels. Each P-DMA controller uses a single data-transfer engine that is shared by the associated channels. General-purpose channels have a rich interconnect matrix including P-DMA cross triggering, which enables demanding data-transfer scenarios. Dedicated channels have a single triggering input (such as an ADC channel) to handle common transfer needs. M-DMA is used for memory-to-memory data transfers and provides high memory bandwidth for a small number of channels. M-DMA uses a dedicated data-transfer engine for each channel. They support independent accesses to peripherals using the AHB multi-layer bus. 3.1.3 Flash CYT2B6 has 576 KB (448 KB with a 32-KB sector size, and 128 KB with an 8-KB sector size) of code-flash with an additional work-flash of up to 64 KB (48 KB with 2-KB sector size, and 16 KB with 128-B sectors size). Work-flash is optimized for reprogramming many more times than code-flash. Code-flash supports Read-While-Write (RWW) operation allowing flash to be updated while the CPU is active. Both the code-flash and work-flash areas support dual-bank operation for over-the-air (OTA) programming. 3.1.4 SRAM CYT2B6 has 64 KB of SRAM. The SRAM0 controller provides DeepSleep retention in 32-KB increments. 3.1.5 ROM CYT2B6 has 32-KB ROM that contains boot and configuration routines. This ROM enables secure boot and authentication of user flash to guarantee a secure system. Document Number: 002-25756 Rev. *B 3.1.6 Cryptography Accelerator for Security The cryptography accelerator implements (3)DES block cipher, AES block cipher, SHA hash, cyclic redundancy check, pseudo random number generation, true random number generation, galois/counter mode, and a vector unit to support asymmetric key cryptography such as RSA and ECC. Depending on the part number, this block is either completely or partially available or not available at all. See Ordering Information for more details. 3.2 System Resources 3.2.1 Power System The power system ensures that the supply voltage levels meet the requirements of each power mode, and provides a full-system reset when these levels are not valid. Internal power-on reset (POR) guarantees full-chip reset during the initial power ramp. Three Brown-Out Detection (BOD) circuits monitor the external supply voltages (VDDD, VDDA, VCCD). The BOD on VDDD and VCCD are initially enabled and cannot be disabled. The BOD on VDDA is initially disabled and can be enabled by the user. For the external supplies VDDD and VDDA, BOD circuits are software configurable with two settings; a 2.7-V minimum voltage that is robust for all internal signaling and a 3.0-V minimum voltage, which is also robust for all I/O specifications (which are guaranteed at 2.7 V). The BOD on VCCD is provided as a safety measure and is not a robust detector. Three overvoltage detection (OVD) circuits are provided for monitoring external supplies (VDDD, VDDA, VCCD), and overcurrent detection circuits (OCD) for monitoring internal and external regulators. OVD thresholds on VDDD and VDDA are configurable with two settings; a 5.0-V and 5.5-V maximum voltage. Two voltage-detection circuits are provided to monitor the external supply voltage (VDDD) for falling and rising levels, each configurable for one of the 26 selectable levels. All BOD, OVD, and OCD circuits on VDDD and VCCD generate a reset, because these protect the CPUs and fault logic. The BOD and OVD circuits on VDDA can be configured to generate either a reset or a fault. 3.2.2 Regulators CYT2B6 contains two regulators that provide power to the low-voltage core transistors: DeepSleep and core internal. These regulators accept a 2.7–5.5-V VDDD supply and provide a low-noise 1.1-V supply to various parts of the device. These regulators are automatically enabled and disabled by hardware and firmware when switching between power modes. The core internal and core external regulators operate in active mode, and provide power to the CPU subsystem and associated peripherals. DeepSleep The DeepSleep regulator is used to maintain power to a small number of blocks when in DeepSleep mode. These blocks include the ILO and WDT timers, BOD detector, SCB0, SRAM memories, Smart I/O, and other configuration memories. The DeepSleep regulator is enabled when in DeepSleep mode, and the core internal regulator is disabled. It is disabled when XRES_L is asserted (LOW) and when the core internal regulator is disabled. Page 7 of 139 CYT2B6 Datasheet Core internal The core internal regulator supports load currents up to 150 mA, and is operational during device start-up (boot process) and in Active/Sleep modes. counter determine the frequency of the reference clock as well as the upper and lower frequency limits of the monitored clock. If the frequency range comparator detects a stopped clock or a clock outside the specified frequency range, an abnormal state is signaled and either a reset or an interrupt is generated. 3.2.3 Clock System EXT_CLK The CYT2B6 clock system provides clocks to all subsystems that require them, and glitch-free switching between different clock sources. In addition, the clock system ensures that no metastable conditions occur. One of the two GPIO_STD I/Os can be used to provide an external clock input of up to 80 MHz. This clock can be used as the source clock for either the PLL or FLL, or can be used directly by the CLK_HF domain. The clock system for CYT2B6 consists of the 8-MHz IMO, two ILOs, three watchdog timers, a PLL, an FLL, five clock supervisors (CSV), a 3.988- to 33.34 MHz ECO, and a 32.768-kHz WCO. ECO The clock system supports two main clock domains: CLK_HF and CLK_LF. ■ CLK_HFx are the Active mode clocks. Each can use any of the high-frequency clock sources including IMO, EXT_CLK, ECO, FLL, or PLL ■ CLK_LF is a DeepSleep domain clock and provides a reference clock for the MCWDT or RTC modules. The reference clock for the CLK_LF domain is either disabled or selectable from ILO0, ILO1, or WCO Table 3-1. CLK_HF Destinations Name Description CLK_HF0 CPUSS clocks, PERI, and AHB infrastructure CLK_HF1 Event Generator, also available in HSIOM as an output IMO Clock Source The IMO is the frequency reference in CYT2B6 when no external reference is available or enabled. The IMO operates at a frequency of 8 MHz ±1%.
