STLC2500 Datasheet, PDF (1/23 Pages) STMicroelectronics – BLUETOOTH™ SINGLE CHIP

STLC2500
1 FEATURES
■ Bluetooth™ specification compliance: V1.1 and
V1.2
■ Ericsson Licensing Technology Baseband Core
(EBC)
■ Point-to-point, point-to-multi-point (up to 7
slaves) and scatternet capability
■ Asynchronous Connection Oriented (ACL)
logical transport link

2 simultaneous SCO channels
■ Support Pitch-Period Error Concealment (PPEC)
– Improves speech quality in the vicinity of in-
terference
– Improves coexistence with WLAN
– Works at receiver, no Bluetooth implication
■ Adaptive Frequency Hopping (AFH): hopping
kernel, channel assessment as Master and as
Slave
■ Faster Connection: Interlaced scan for Page
and Inquiry scan, first FHS without random back
off, RSSI used to limit range
■ Extended SCO (eSCO) links

13, 26, 19.2 or 38.4 MHz
– LPO clock input at 3.2, 16.384, 32 or 32.768 kHz
■ ARM7TDMI CPU
– 32-bit Core
– AMBA (AHB-APB) bus configuration
■ Patch RAM capability
■ Memory organization
– On chip RAM, including provision for patches
– On chip ROM, preloaded with SW up to HCI
■ Communication interfaces
– Fast UART
– PCM interface
– 4 programmable GPIOs
– External interrupts possible through the GPIOs
– Fast master I2C interface
■ Efficient support for WLAN coexistence in
collocated scenario
■ Ciphering support up to 128 bits key

etary extensions)
– HCI proprietary commands (e.g. peripherals
control)
– Single HCI command for patch/upgrade download
■ Single power supply with internal regulators for
core voltage generation
■ Supports 1.65 to 2.85 Volts IO systems
■ Total number of external components limited to 7
(6 decoupling capacitors and 1 filter) thanks to:
– Fully integrated synthesizer (VCO and loop filter)
– Integrated antenna switch
– Low IF receiver
■ Auto calibration (VCO, Filters)
■ No need for calibration of the RF part
■ Timer and watchdog
■ Power class 2 compatible
■ Ultra low power architecture with 3 different low
power levels:
– Sleep Mode
– Deep Sleep Mode
– Complete Power Down Mode
■ Software Initiated Low Power Mode
■ Dual Wake-up mechanism: initiated either by
the Host or by the Bluetooth device
■ Standard TFBGA-84 pins package
2 DESCRIPTION
The STLC2500 is a single chip ROM-based Blue-
tooth solution implemented in 0.13 m ultra low
power, low leakage CMOS technology for applica-
tions requiring integration up to HCI level. Patch
RAM is available enabling multiple patches/up-
grades.
The STLC2500's main interfaces are UART for
HCI transport, PCM for voice and GPIOs for con-
trol purposes. The Radio is designed for the single
chip requirement and for drastic power consump-
tion reduction.
