Real-Time Clock (RTC) module for recording and storing time and date
Epson Toyocom has announced the development of the RX-5412SF, a real-time clock module equipped with a time-stamp function for recording and storing the times and dates of abnormal events such as system errors and warning signals. Commercial development is scheduled for the first half of 2009.
The time-stamp function built into the RX-5412SF detects and records signals generated when an error or emergency event occurs. Time-stamping improves system reliability and can be applied in a wide range of fields, from quality control to security. The demand for time-stamping has been accelerating in recent years, driven by, among other things, an intensified interest in security technologies in response to the spread of a diverse range of computer crimes, and by public concern about the safety and tracing of food supplies.
Time-stamping generally is provided by microprocessor systems. However, with CPU resources limited, the task of developing complex software that is also reliable has been a major burden. To alleviate this burden, Epson Toyocom developed the RX-5412SF real -time clock module so that time-stamping can easily be incorporated into a system. In addition to giving customers added freedom in the use of CPU resources and reducing time and effort spent in software development, the RX-5412SF will help save costs and improve system reliability.
The RX-5412SF has four input pins and can record the date and time along with identifying information for each pin. The other features of this module includes, general-purpose memory, a 256-byte SRAM chip that can be used as a time-stamp memory, a watchdog timer, a general-purpose timer and power switching.
A backup battery enables timekeeping and time-stamping to continue even if a system goes down on a weekend, at night, or during a power failure.
Main Features
1. Full calendar and clock functions with automatic leap year correction
2. Built-in 32.768 kHz crystal unit eliminates the need for clock accuracy adjustments
3. Alarms settable for dates, days of the week, hours and minutes
4. A fixed-cycle timer that can be set for any time between 244.14 micro-seconds and 4095 minutes
5. Power switching function for automatically switching to a backup power source when the voltage of the main power supply drops
6. Built-in general-purpose memory and 256-bytes of RAM that can be used for time-stamp memory
7. Capable of 4-input event detection with adjustable chattering-free *2 sensitivity, and able to output interrupt signals during input detection
8. Watchdog timer settable from 1.95 ms to 468.75 ms
Key specifications
Supply voltage 2.5 V to 5.5 V
Clock voltage 1.4 V to 5.5 V
Standby current consumption 0.5 µA (Typ.) / 3 V
Frequency precision 5±23 x 10 -6
Interface 4-wire serial
External dimensions 10.2 x 5.4 x 2.0t mm (24-pin SSOP)
