reprogramable ROM

• Includes 6 KB of RAM

Tuner Block

LC87F5BP6A (Flash Version)

FM multiplex broadcasting is a new data transmission system that allows reception by mobile
receivers and features a large transmission capacity and a wide service area.
SANYO has proposed ICs that exactly match the requirements of each functional block and is
now aiming at further product line expansion in this area.
