Si1000/1/2/3/4/5
1. System Overview
Si1000/1/2/3/4/5 devices are fully integrated mixed-signal system-on-a-chip MCUs. Highlighted features
are listed below. Refer to Table 2.1 for specific product feature selection and part ordering numbers.

With on-chip power-on reset, V
devices are truly standalone system-on-a-chip solutions. The Flash memory can be reprogrammed even
in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. User
software has complete control of all peripherals, and may individually shut down any or all peripherals for
power savings.
The on-chip Silicon Labs 2-Wire (C2) Development Interface allows non-intrusive (uses no on-chip
resources), full speed, in-circuit debugging using the production MCU installed in the final application. This
debug logic supports inspection and modification of memory and registers, setting breakpoints, single
stepping, and run and halt commands. All analog and digital peripherals are fully functional while debug-
ging using C2. The two C2 interface pins can be shared with user functions, allowing in-system debugging
without occupying package pins.
Each device is specified for 1.8 to 3.6 V operation over the industrial temperature range (–40 to +85 °C).
The Port I/O and RST pins are tolerant of input signals up to 5 V. The Si1000/1/2/3/4/5 are available in a
42-pin QFN package (lead-free and RoHS compliant). See Table 2.1 for ordering information. Block dia-
grams are included in Figure 1.1 through Figure 1.6.
The transceiver's extremely low receive sensitivity (–121 dBm) coupled with industry leading +20 dBm out-
put power ensures extended range and improved link performance. Built-in antenna diversity and support
for frequency hopping can be used to further extend range and enhance performance. The advanced radio
features including continuous frequency coverage from 240–960 MHz in 156 Hz or 312 Hz steps allow pre-
cise tuning control. Additional system features such as an automatic wake-up timer, low battery detector,
64 byte TX/RX FIFOs, automatic packet handling, and preamble detection reduce overall current con-
sumption. The transceivers digital receive architecture features a high-performance ADC and DSP-based
modem which performs demodulation, filtering, and packet handling for increased flexibility and perfor-
mance. The direct digital transmit modulation and automatic PA power ramping ensure precise transmit
modulation and reduced spectral spreading, ensuring compliance with global regulations including FCC,
ETSI, ARIB, and 802.15.4d regulations.
An easy-to-use calculator is provided to quickly configure the radio settings, simplifying customer's system
design and reducing time to market.
