General Description
The SEC1110 and SEC1210 provide a single-chip solu-
tion for a Smart Card bridge to USB and UART inter-
faces. These bridges are controlled by an enhanced
8051 micro controller and all chip peripherals are
accessed and controlled through the SFR or XDATA
register space. TrustSpan
TM
Technology enables digital
systems to securely communicate, process, move and
store information on system boards, across networks
and through the cloud.
Feature Highlights
• Smart Card
- The SEC1110 provides one Smart Card inter-
face and the SEC1210 provides two
- Fully compliant with ISO/IEC 7816, EMV 4.2/
4.3, ETSI TS 102 221 and PC/SC standards
- Versatile ETU rate generation, supporting cur-
rent and proposed rates (up to 826 Kbps)
- Full support of both T=0 and T=1 protocols
- Full-packet FIFO (261 bytes), for transmit and
receive
- Half-duplex operation (no software interven-
tion required between transmit and receive
phases of exchange)
- Loose real-time response required of software
(approximately 180 ms)
- Dynamically programmable FIFO threshold
with byte granularity
- Time-out FIFO flush interrupt, independent of
threshold
- Programmable Smart Card clock frequency
- UART-like register file structure
- Supports Class A, Class B, Class C, or Class
AB Smart Cards (1.8V, 3.0V and 5.0V cards)
- Automatic character repetition for T=0 proto-
col parity error recovery
- Automatic card deactivation on card removal
and on other system events, including per-
sistent parity errors
- Internal procedure byte filtering for T=0 proto-
col
- Protocol timers (Guard, Timeout, and CWT)
for EMV-defined timing parameters
–Detection of an unresponsive card
–Activation/deactivation sequences
–Cold/warm resets
–Monitoring for all EMV timing constraints
–16-bit general purpose down counter for software
timing use
- Fully compliant ESD protection on card pins
•USB
- 12 Mbps USB operation compliant to the USB
2.0 Specification
- Integrated USB 1.5 K pull-up resistor and
Dp,Dm series termination resistors
- Integrated USB devices controller with:
–8/16/32/64 byte control buffer
–Five 8/16/32/64 byte programmable (bulk/interrupt)
endpoint buffers
• 8051 Processor
- Reduced instruction cycle time (approximately
9 times 80C51)
- 9.6 MHz max clock speed
- Enhanced peripherals; three 16-bit timers,
watchdog timer, interrupt controller, JTAG
- OTP (One Time Programmable)
ROM: 16 KB RAM: 1.5 KB
• Boot ROM: 16 KB UART (SEC1210 only)
— Standard PC baud rates supported
— 3 M baud high-speed rate (not PC standard)
• SPI (SEC1210 only)
- Host capability with 12 MHz max performance
• General
- 5.0 V tolerance on user accessible IO pins
- Self-clocking internal oscillator, no external
crystal required
- 3.6V - 5.5V supply input
–Internal 4.8V comparator disables Class A card
support if the input voltage is too low
- Available in commercial (0ºC to +70ºC) and
industrial (-40ºC to +85ºC) temperature
ranges
Applications
• USB Smart Card reader
• UART-based Smart Card reader
• Dual Smart Card reader
Host/Smart Card Interface Overview
