S6E2C2 Datasheet, PDF (5/207 Pages) Cypress Semiconductor – 32-bit ARM® Cortex®-M4F FM4 Microcontroller

S6E2C2 Series
Low-power Consumption Mode
Six low power consumption modes are supported.
 Sleep
 Timer
 RTC
 Stop
Deep standby RTC (selectable from with/without RAM
retention)
Deep standby stop (selectable from with/without RAM
retention)
Peripheral Clock Gating
The system can reduce the current consumption of the total
system with gating the operation clocks of peripheral functions
not used.
VBAT
The consumption power during the RTC operation can be
reduced by supplying the power supply independent from the
RTC (calendar circuit)/32 kHz oscillation circuit. The following
circuits can also be used.
 RTC
32-kHz oscillation circuit
Power-on circuit
Back up register: 32 bytes
Port circuit
Crypto Assist Function
The following function is built in as Crypto Assist Function.
The dedicated middleware is necessary for this calculator
operation.
PKA (Public Key Accelerator)
 PKA（Public Key Accelerator）is modular exponentiation
calculation accelerator used of RSA Public Key crypto and
so on.
 Available bit length: Up to 2048-bit
AES calculator
 AES (Advanced Encryption Standard) calculator is a AES
common key crypto accelerator which is compliant with
FIPS (Federal Information Processing Standard
Publication )197.
 Available key length: 128/192/256-bit
 CBC mode and ECB mode support
SHA-256 calculator
 SHA-256 calculator is a SHA-256 hash function
accelerator which is compliant with FIPS180-2.
External Bus Data Scramble
 It enables to scramble input/output data of External Bus
Interface.
Debug
Serial wire JTAG debug port (SWJ-DP)
Embedded trace macrocells (ETM) provide comprehensive
debug and trace facilities.
AHB trace macrocells (HTM)
Unique ID
Unique value of the device (41-bit) is set.
Power Supply
Five power supplies
 Wide range voltage:
VCC
= 2.7 V to 5.5 V
 Power supply for USB ch 0 I/O:
USBVCC0 = 3.0 V to 3.6 V (when USB is used)
= 2.7 V to 5.5 V (when GPIO is used)
 Power supply for USB ch 1 I/O:
USBVCC1 = 3.0 V to 3.6 V (when USB is used)
= 2.7 V to 5.5 V (when GPIO is used)
 Power supply for Ethernet-MAC I/O:
ETHVCC = 3.0 V to 5.5 V (when Ethernet is used.)
= 2.7 V to 5.5 V (when GPIO is used)
 Power supply for VBAT:
VBAT
= 1.65 V to 5.5 V
