Part Name(s) : SM6780AS
NPC
Nippon Precision Circuits
Description : Ni-Cd/Ni-MH Battery Charger IC

OVERVIEW
The SM6780AS is a quick charge control IC for Nickel-Cadmium (Ni-Cd) and Nickel Metal Hydride (Ni-MH) Rechargeable batteries. It supports quick charge, supplemental and pulse trickle charging modes. The charging mode is selected automatically in response to the Battery voltage, temperature and charging time.

FEATURES
■ Ni-Cd/Ni-MH Battery quick charge control
■ −∆V, ∆T/∆t, and maximum charge time cutoffs
■ 3 charge modes (quick charge, supplemental, pulse trickle charge)
■ 3 selectable charge times (80, 120, and 240 minutes)
■ Charge condition LED indicator output (on, pulsed, off)
■ Low power dissipation mode
■ 4.0 to 5.5V operating supply voltage
■ 300sec (typ) −∆V detection invalid time
■ 8mV (typ) −∆V detection accuracy
■ 25mV/min (typ) ∆T/∆t detection accuracy
■ 8-pin SOP package

Part Name(s) : SM6781BV
NPC
Nippon Precision Circuits
Description : Ni-MH/Ni-Cd Battery Charger IC

OVERVIEW
The SM6781BV is a quick charge control IC for Nickel Metal Hydride (NiMH) and Nickel-Cadmium (NiCd) Rechargeable batteries. Quick charging ends in response to negative delta voltage detection (–∆V) and maximum charging time detection functions. Also, quick charge mode is placed on hold if the Battery voltage becomes abnormal, until normal conditions are restored. The SM6781BV requires few external components to realize a high-stability quick charge Battery charger.

FEATURES
Ni-MH/Ni-Cd Battery quick charge control
■ −∆V and maximum charge time cutoffs
■ 15min (typ) −∆V detection invalid time
■ – 4mV (typ) −∆V detection accuracy
■ Inhibit function
■ Charge condition LED indicator output (on, pulsed, off)
■ Low power dissipation standby mode (< 1µA)
■ 8-pin VSOP package

Description : 4-Bit Microcontroller with Built-in LCD Driver and Melody Circuit

GENERAL DESCRIPTION
The MSM64P155 (1.5 V)/64P155L (3.0 V) is a one-time-programmable ROM version product, which has one-time PROM (OTP) as internal program memory. On the other hand, the MSM64155 is a mask ROM-version product, which has mask ROM as internal program memory. Unlike the mask ROM-version MSM64155 which has a P-well CMOS structure, the MSM64P155/64P155L has been fabricated with the N-well CMOS-structured EPROM process technology.
Therefore, the MSM64P155/64P155L differs from the MSM64155 in the polarity of the power supply for LCD bias generation and in the external circuit structure.
Unlike the mask ROM-version product, the MSM64P155/64P155L cannot be supplied in the form of a chip. The MSM64P155/64P155L is an OTP-version product used to evaluate an application program.
The MSM64P155/64P155L has two operation modes, microcontroller operation mode and PROM mode. The microcontroller operation mode is used to operate the MSM64P155/64P155L like a mask ROM-version product and the PROM mode is used to program or read the PROM.
