CD1005 chip is an industrial digital electronic
detonator control chip launched by Shanghai ChipDance Technology Co., Ltd. It
can control the energy storage capacitor, ignition switch and other peripheral
devices on the electronic detonator module according to the instructions sent
by the detonator through the bus, and realize large-scale, high-precision
timing detonation.
Typical operating current < 7μA
Built-in RC oscillator with a frequency of 200KHz
CD1003 integrates an OSC, LDO, memory, digital control module, charging and discharging module, etc.
Besides the firing element and energy storage capacitor, the module requires only 7 peripheral components, demonstrating a high degree of integration.
Supports online import of detonator information by the Blaster, eliminating the need for scan code registration.(Depend on local regulations.)
Capable of storing and lock critical information such as the UID, shell code, and detonation password of electronic detonators.
Supports networking of 1000 detonators in parallel on a 2000m cord per one Blaster.
Supports cascading networking of 128 Blasters.
Delays under 150ms with precision < 0.3ms.
Delays over 150ms with precision < 2‰.
Operates within a wide voltage range of 7V-40v.
Suitable for operating environments from -40℃~85℃.
Reliable communication distance exceeds 2000m.
Compatible with parallel cables, aluminium wires, and other unconventional bus lines without polarity distinction.
Provides 9 voltage levels for precise control of energy storage capacitor voltage.
Maximum delay programming value of 65000ms, within a minimum programming interval of 1ms.
Optimized for interference from the bus to enhance reliability in specific scenarios.
Supports third-party production of UID and random password services.
Integrated functionality for measuring the capacitance of energy storage capacitors.
Integrated functionality for checking the continuity of firing elements.
Key parameter status monitoring and self-diagnosis.
Query time for online status of 1000 electronic detonators as low as 500ms.
Full process detection of electronic detonator misconnections, multiple connections, and disconnections during networking, charging, and detonation.
Communication capacitor of 4.7μF
Communication voltage between 8V and 10V.
During network detection, UID matching verification, authorization checks, password validation, and delay scheme verification, the energy capacitor does not charge.
