Si4010
1. System Overview
The Si4010 is a fully integrated crystal-less CMOS SoC RF transmitter with an embedded CIP-51 8051
MCU designed for the sub 1 GHz ISM frequency bands. This chip is optimized for battery powered applica-
tions with operating voltages from 1.8 to 3.6 V and ultra-low current consumption with a standby current of
less than 10 nA. The high power amplifier can supply up to +10 dBm output power with 19.5 dB of pro-
grammable range. Moreover, the SoC transmitter includes a patented antenna tuning circuit that automati-
cally fine tunes the resonance frequency and impedance matching between the PA output and the
connected antenna for optimum transmit efficiency and low harmonic content. FSK and OOK modulation is
supported with symbol rates up to 100 kbps. Like all wireless devices, users are responsible for complying
with applicable local regulatory requirements for radio transmissions.
The embedded CIP-51 8051 MCU provides the core functionality of the Si4010. User software has com-
plete control of all peripherals, and may individually shut down any or all peripherals for power savings. A
space of 8 kB of on-chip one-time programmable NVM memory is available to store the user program and
can also store unique transmit IDs. In case of power outages due to battery removal, 128 bits of EEPROM
is available for counter or other operations providing non-volatile storage capability. A library of useful soft-
ware functions such as AES encryption, a patented 32-bit counter providing 1 M cycles of read/write
endurance, and many other functions are included in the 12 kB of ROM to reduce user design time and
code space. General purpose input/output pins with push button wake-on touch capability, a programma-
ble system clock, and ultra low power timers are also available to further reduce current consumption.
The Si4010 includes Silicon Laboratories' 2-wire C2 Debug and Programming interface. This debug logic
supports memory inspection, viewing and modification of special function registers (SFR), setting break
points, single stepping, and run and halt commands. All analog and digital peripherals are fully functional
while debugging using C2. The two C2 interface pins can be shared with user functions, allowing in-system
debugging without occupying package pins.
The device leverages Silicon Labs' patented and proven crystal-less oscillator technology and offers better
than ±150 ppm carrier frequency stability over the temperature range of 0 to + 70 °C and ±250 ppm carrier
frequency stability over the industrial range of –40 to + 85 °C without the use of an external crystal or fre-
quency reference. The internal MCU automatically calibrates the on-chip voltage controlled oscillator
(LCOSC) which forms the output carrier frequency for process and temperature variations. An external 1-
pin crystal oscillator option is available for applications requiring tighter frequency tolerances.
Digital integration reduces the amount of required external components compared to traditional offerings,
resulting in a solution that only requires a printed circuit board (PCB) implementation area of approximately
25 by 50 mm (including battery, switches, and 25 mm2 antenna). The high integration of the Si4010
improves the system manufacturing reliability and quality and minimizes costs. This chip offers industry
leading RF performance, high integration, flexibility, low BOM, small board area, and ease of design. No
production alignment is necessary as all RF functions are integrated into the device.
